in the plain at the north-east corner, and rather further |
south the conical hill called Neby Duby rises between Tabor
and Gilboa. The whole of Lower Galilee is well watered.
The Kishon is fed by springs from near Tabor and from a
copious stream from the west side of the plain of Esdraelon.
North-west of Nazareth is Wâdy el Melek, an open valley
full of springs. The river Belus, just south of Acre, rising
in the sea-coast marshes, drains the whole valley of Jiphthah-
el. On the east the broad valley of Jezreel is full of
magnificent springs, many of which are thermal. The
plains of Esdraelon, and the Buttauf, and the plateau of el
Ahma, are all remarkable for the rich basaltic soil which
covers them, in which corn, cotton, maize, sesame, tobacco,
millet, and various kinds of vegetable are grown, while
indigo and sugar-cane were cultivated in former times. The
Nazareth hills and Gilboa are bare and white, but west of
Nazareth is a fine oak wood, and another thick wood
spreads over the northern slopes of Tabor. The hills west
of the great plain are partly of bare white chalk, partly
covered with dense thickets. The mountains north of the
Buttauf are rugged and covered with scrub, except near the
villages, where fine olive groves exist. The principal places
of importance in Lower Galilee are Nazareth (10,000
inhabitants), Sepphoris (now Seffûrieh), a large village
standing above the Buttauf on the spurs of the southern hills,
and Jenîn (En Gannim), a flourishing village, with a palm
garden (3000 inhabitants). The ancient capital, Jezreel
(Zerin), is now a miserable village on a precipitous spur of
Gilboa; north of this are the small mud hamlets, Solam
(Shunem), Endûr (Endor), Nein (Nain); on the west side
of the plain is the ruin of Lejjûn (the Legio of the 4th
century, which was then a place of importance). In the
hills north of the Buttauf is Jefât, situated on a steep hill-
top, and representing the Jotapata defended by Josephus.
Kefr Kenna, now a flourishing Christian village at the foot
of the Nazareth hills, south of the Buttauf, represents the
probable site of Cana of Galilee, and the ruin Kâna, on the
north side of the same plain, represents the site pointed out
to the pilgrims of the 12th and 13th centuries.

Hazor, has been found by the survey party in 1877 apply-
ing to a mountain and plain, near an ancient ruin, in the
required position. The little village of Kades represents
the once important town of Kadesh Naphtali (Josh. xix.
37). The ruins are here extensive and interesting, but
belong apparently to the Greek period.

The population of Galilee is mixed. In Lower Galilee
the peasants are principally Moslem, with a sprinkling of
Greek Christians round Nazareth, which is a Christian
town. In Upper Galilee, however, there is a mixture of
Jews and Maronites, Druses and Moslems (natives or
Algerine settlers), while the slopes above the Jordan are
inhabited by wandering Arabs. The Jews are engaged in
trade, and the Christians, Druses, and Moslems in agricul-
ture; and the Arabs are an entirely pastoral people.

The principal products of the country are corn, wine, oil, and soap (from the olives), with every species of pulse and gourd.

The antiquities of Galilee include cromlechs and rude. stone monuments, rock-cut tombs, and wine-presses, with numerous remains of Byzantine monasteries and fine churches of the time of the crusades. There are also remains of Greek architecture in various places, but the most interesting buildings are the ancient synagogues. These have not been found in other parts of Palestine, but in Galilee eleven examples are now known, They are rectangular, with the door to the south, and three rows of columns forming four aisles east and west. The architecture is a peculiar and debased imitation of classic style, attributed by architects to the 2d century of our era. The builder of the examples at Kefr Birim, el Jish, and Meirûn is known to have been the famous Simeon bar Jochai, who lived about 150 A.D., and built 24 synagogues in Galilee. The similarity of style renders it probable that the other examples at Tell Hûm, Kerâzeh, Ñebartein, Umm el 'Amed, and Sufsâf were also his work. Both at el Jish and at Kefr Birim there are two synagogues, large and small. At Irbid, above Tiberias, is another synagogue of rather different character, which is said to have been built by Rabbi Nitai. Traces of synagogues have also been found on Carmel, and at Tireh, west of Nazareth. It is curious to find the representation of various animals in relief on the lintels of these buildings. Hebrew inscriptions also occur, and the carved work of the cornices and capitals is very rich. These synagogues were erected at a time when the Galilean Jews were flourishing under the Roman empire, and when Tiberias was the central seat of Jewish learning and of the Sanhedrin.

Upper Galilee.The mountains are tilted up towards the sea of Galilee, and the drainage of the district is towards the north-west. On the south the rocky range of Jebel Jermuk rises to 4000 feet above the sea; on the east a narrow ridge 2800 feet high forms the watershed, with steep eastern slopes falling towards Jordan. Immediately west of the watershed are two small plateaus, covered with basaltic debris, near el Jish and Kades. On the west are rugged mountains with deep intricate valleys. The main In the 12th century Galilee was the outpost of the Chrisdrains of the country are-first, Wâdy el 'Ayûn, rising north tian kingdom of Jerusalem, and its borders were strongly of Jebel Jermûk, and running north-west as an open valley, protected by fortresses, the magnificent remains of which and secondly, Wâdy el Ahjâr, a rugged precipitous gorge still crown the most important strategical points.

shaped, 12 English miles in length, and 7 at its greatest width. The level is now known to be 682.5 feet below the Mediterranean. The water is fresh and clear, and large shoals of fish abound in it. The formation of the lake basin occurred later than the Chalk period, and was due to a subsidence of the strata, which appears to have been sudden and violent, and probably accompanied by extensive volcanic eruptions from three centres east, west, and north of the lake. The district has always been liable to volcanic disturbance and to earthquakes. In 1837 Safed and Tiberias were destroyed by earthquake, and the temperature of the hot springs round the lake was then observed to rise considerably for a time,

The Sea of Galilee is best seen from the top of the western precipices, and presents a desolate appearance. On the north the hills rise gradually from the shore, which is fringed with oleander bushes and indented with small bays. The ground is here covered with black basalt. On the west the plateau of el Ahma terminates in precipices 1700 feet above the lake, and over these the black rocky tops called "the Horns of Hattîn " are conspicuous objects. the south is a broad valley through which the Jordan flows. On the east are furrowed and rugged slopes, rising to the great plateau of the Jaulan (Gaulonitis). The Jordan enters the lake through a narrow gorge between lower hills. A marshy plain, 2 miles long and 1 broad, called el Batihah, exists immediately east of the Jordan inlet. There is also on the west side of the lake a small plain called el Ghuweir, formed by the junction of three large

wide. This plain, naturally fertile, but now almost uncultivated, is recognized to be the plain of Gennesareth, described by Josephus (B. J., iii. 10, 8). The shores of the lake are of fine shingle. On the east the hills approach in one place within 40 feet of the water, but there is generally a width of about of a mile from the hills to the beach. On the west the flat ground at the foot of the hills has an average width of about 200 yards. A few scattered palms dot the western shores, and a palm grove is to be found near Kefr Hârib on the south-east. Thermal springs are found. on each side of the lake, with an average temperature of about 80° Fahr. The hot baths south of Tiberias include seven springs, the largest of which has a temperature of 137° Fahr. The plain of Gennesareth, with its environs, is the best watered part of the lake-basin. North of this plain are the five springs of et Tabghah, the largest of which was enclosed about a century ago by Aly, son of Dhahr el 'Amr, in an octagonal reservoir, and the water led off by an aqueduct 52 feet above the lake. The Tabghah springs, though abundant, are warm and brackish. At the north end of the plain is 'Ain et Tîneh ("spring of the fig-tree"), also a brackish spring with a good stream; south of the plain is 'Ain el Bârdeh ("the cold spring"), which is sweet, but scarcely lower in temperature than the others. The most important spring remains still to be noticed, namely, 'Ain el Madâwerah ("the round spring"), situated 1 mile from the south end of the plain and half a mile from the shore. The water rises in a circular well 32 feet in diameter, and is clear and sweet, with a temperature of 73° Fahr. The bottom is of loose sand, and the fish called coracinus by Josephus (B. J., iii. 10, 8) is here found in abundance. Dr Tristram was the first explorer to identify this fish, and points out that it could not exist in the other springs. We are thus able to identify the "round spring" with the fountain of Capharnaum, which, according to Josephus, watered the plain of Gennesareth.

The principal sites of interest round the lake may be enumerated from north to west and from south to east. Kerâzeh, the undoubted site of Chorazin, stands on a rocky spur 900 feet above the lake, 2 miles north of the shore. Foundations and scattered stones cover the slopes and the flat valley below. On the west is a rugged gorge. In the middle of the ruins are the remains of a synagogue of richly ornamental style built of black basalt. A small spring occurs on the north. Tell Hûm is an important ruin on the shore south of the last mentioned site. The remains consist of foundations and scattered stones (which in spring are concealed by gigantic thistles) extending about half a mile along the shore. The foundations of a fine synagogue, measuring 75 feet by 57, and built in white limestone, have been excavated. A conspicuous building has been erected close to the water, from the fragments of the Tell Hûm synagogue. Since the 4th century Tell Hûm has been pointed out by all the Christian writers as the site of Capernaum, but the fatal objections to such an identification are-(1) the great distance from the fountain of Capharnaum, and (2) the fact that Jewish tradition preserves another site. The ruins at Tell Hum are not of necessity as old as the time of Christ. The name Hum means "black," and is probably connected with the surrounding black basalt. The place seems to be mentioned in the Talmud under the titles Caphar Ahim and Caphar Tanhumin (see Neubauer's Geog. Tal., p. 220). Minyeh is a ruined site at the north end of the plain of Gennesareth, 2 miles from the last, and close to the shore. There are extensive ruins on flat ground, consisting of mounds and foundations, with traces of a wall once surrounding the site. Masonry of well-dressed stones has also been here discovered in course of excavation. Near the ruins are remains of an old khân, which appears to have

been built in the Middle Ages; and above this a curious | rocky spur opposite Tiberias. Two large ruined buildings
hillock, with an artificial rock-platform, called el 'Oreimeh,
"the little knoll." Immediately to the north-east a preci-
pice projects to the lake, and the aqueduct from the Tâbghah
spring is led to an ancient rock-cut channel, which seems to
have been once intended for a road in the face of the cliff.
In the 17th century Quaresmius speaks of this place,
Minyeh, as the site of Capernaum. In the 14th Isaac
Chelo was apparently shown the same site as containing the
tomb of Nahum, and as being the "city of the Minai." The
"Minai," or "sorcerers," are mentioned in the Talmud, and
by this title the Jews stigmatized the early Christians; and
these "Minai" are called in one passage of the Talmud
"sons of Capernaum." There is thus a close connexion
between this Minyeh-named from the Minai-and the
town of Capernaum. The position of the site is also
suitable for that of Capernaum, being in the plain of
Gennesareth, two miles from the "round spring," or
fountain of Capharnaum. No other site of any importance
exists in the plain of Gennesareth. See CAPERNAUM.

South of the plain of Gennesareth is the undisputed site of the New Testament town of Magdala. A few lotus trees and some rock-cut tombs are here found beside a miserable mud hamlet on the hill slope, with a modern tomb-house or kubbeh. Passing beneath rugged cliffs a recess in the hills is next reached, where stands Tabarîya, the ancient Tiberias or Rakkath, containing 3000 inhabitants, more than half of whom are Jews. The walls, flanked with round towers, and now partly destroyed by the earthquake of 1837, were built by Dhahr el 'Amr, as was the serai or court-house. The two mosques, now partly ruinous, were erected by his sons. There are remains of a crusading church, and the tomb of the celebrated Maimonides is shown in the town, while Rabbi Akiba and Rabbi Meir lie buried outside, The ruins of the ancient city, including granite columns and traces of a sea-wall with towers, stretch southwards a mile beyond the modern town. An aqueduct in the cliff once brought water a distance of 9 miles from the south.

remain, with traces of an old street and fallen columns and
capitals. A strong wall once surrounded the town; a
narrow neck of land exists on the east where the rock has
been scarped. Rugged valleys enclose the site on the north
and south; broken sarcophagi and rock-cut tombs are
found beneath the ruin. This site answers to the de-
scription Josephus gives of Gamala, an important fortress
besieged by Vespasian (Bell. Jud., iv. 1, 1). Gersa, an
insignificant ruin north of the last, is thought to represent
the Gerasa or Gergesa of the 4th century, situated east of
the lake; and the projecting spur of hill south of this ruin
is conjectured to be the place where the swine ran
violently down a steep place" (Matt. viii. 32). The site
of Bethsaida Julias, east of Jordan, is also unknown.
has been supposed (and the theory is supported by even
so important an authority as Reland) that two separate
places named Bethsaida are mentioned in the New Testa-
ment. The grounds for this conclusion are, however, very
insufficient; and only one Bethsaida is mentioned by
Josephus. It was near the Jordan inlet, on the east side
of the river, and under its later Greek name of Julias, it is
mentioned, with Hippos, by Pliny. The site usually pointed
out is the ruin of et Tell, north of the Batîhah plain; the
remains are, however, modern and insignificant. Just south
of the same plain is a ruined village called Mes'aidîyeh, the
name of which approaches Bethsaida in sound but not in
meaning. This is the site pointed out by Vandevelde, and
it is possible that the course of Jordan has shifted west-
wards, and that the old mouth is marked by the two creeks
running into the shore on the east, in which case the site
of Mes'aidîyeh might be accepted as the Bethsaida of the
gospels, which appears to have been east of Jordan.

Kerak, at the south end of the lake, is an important site on a peninsula surrounded by the water of the lake, by the Jordan, and by a broad water ditch, while on the north-west a narrow neck of land remains. The plateau thus enclosed is partly artificial, and banked up 50 or 60 feet above the water. A ruined citadel remains on the north-west, and on the east was a bridge over the Jordan; broken pottery and fragments of sculptured stone strew the site. The ruin of Kerak answers to the description given by Josephus of the city of Tariches, which lay 30 stadia. from Tiberias, the hot baths being between the two cities. Tarichea was situated, as is Kerak, on the shore below the cliffs, and partly surrounded by water, while before the city was a plain (the Ghôr). Pliny further informs us that Tariche was at the south end of the Sea of Galilee. Sinnabreh, a ruin on a spur of the hills close to the lastmentioned site, is undoubtedly the ancient Sinnabris, where Vespasian (Joseph., B. J., iii. 9, 7) fixed his camp, advancing from Scythopolis (Beisân) on Tariches and Tiberias. Sinnabris was 30 stadia from Tiberias, or about the distance of the ruin now existing.

Literature. The most important works on the subject of Galilee
and the Sea of Galilee are the following:-Robinson's Biblical
Researches; Stanley's Sinai and Palestine; Tristram's Land of
Israel; Warren and Wilson's Recovery of Jerusalem; Conder's Tent
Work in Palestine; and the Memoirs of the Survey of Palestine
(sheets 1-6, 8, 9).
(C. R. C.)

The eastern shores of the Sea of Galilee have been less fully explored than the western, and the sites are not so perfectly recovered. The town of Hippos, one of the cities of Decapolis, was situated 30 stadia from Tiberias, and 60 stadia from Gadara (Umm Keis). It is conjectured that the town Susitha, mentioned in the Talmud, is the same place, and the name Susyeh seems to have existed east of the Sea of Galilee at a late period. Susitha from "sus," meaning "horse," is, etymologically at least, suggestive of the Greek "hippos." The site is at present unknown. Kalat el Hosn ("castle of the stronghold") is a ruin on a

GALILEO. Galileo Galilei (1564-1642), one of the earliest and greatest of experimental philosophers, was born at Pisa, February 18, 1564. His father, Vincenzo, was an impoverished descendant of a noble Florentine house, which had exchanged the surname of Bonajuti for that of Galilei, on the election, in 1343, of one of its members, Galileo de' Bonajuti, to the college of the twelve Buonuomini. The family, which was fifteen times represented in the signoria, and in 1445 gave a gonfalonier to Florence, flourished with the republic and declined with its fall. Vincenzo Galilei was a man of better parts than fortune. He was a competent mathematician, wrote with considerable ability on the theory and practice of music, and was especially distinguished amongst his contemporaries for the grace and skill of his performance upon the lute. By his wife, Giulia de' Ammannati of Pistoja, he had two sons, Galileo and Michelangiolo, and two daughters, Virginia and Livia. From his earliest childhood Galileo was remarkable for intellectual aptitude, as well as for mechanical invention. His favourite pastime was the construction of toy-machines, not the less original and ingenious that their successful working was usually much hindered by the scarcity of suitable materials. His application to literary studies was equally conspicuous. In the monastery of Vallombrosa, near Florence, where his education was principally conducted, he not only made himself acquainted with the best Latin authors, but acquired a fair command of the Greek tongue, thus laying the foundation of the brilliant and elegant style for which his writings were afterwards distinguished. From one of the monks he also received instruction in logic, according to the system then in vogue; but the futilities of the science revolted, while its subtleties

failed to interest his understanding, and he was soon permitted to abandon a study so distasteful to him. A document published by M. Selmi in 1864 proves that he was at this time so far attracted towards a religious life as to have joined the novitiate of the order; but his father, who had other designs for him, seized the opportunity of an attack of ophthalmia to withdraw him permanently from the care of the monks. Having had personal experience of the unremunerative character both of music and of mathematics, he desired that his son should apply himself to the more profitable study of medicine, and, not without some straining of his slender resources, placed him, before he had completed his eighteenth year, at the university of Pisa. He accordingly matriculated, November 5, 1581, and immediately entered upon attendance at the lectures of the celebrated physician and botanist, Andrea Cesalpino.

From the leaning tower of Pisa he afforded to all the professors and students of the university ocular demonstration of the falsehood of the Peripatetic dictum that heavy bodies fall with velocities proportional to their weights, and with unanswerable logic demolished all the time-honoured maxims of the schools regarding the motion of projectiles, and elemental weight or levity. But while he convinced, he failed to conciliate his adversaries. The keen sarcasm of his polished rhetoric was not calculated to soothe the susceptibilities of men already smarting under the deprivation of their most cherished illusions. He seems, in addition, to have compromised his position with the grand-ducal family by the imprudent candour with which he condemned a machine for clearing the port of Leghorn, invented by Giovanni de' Medici, an illegitimate son of Cosmo I.

In 1586 he was withdrawn from the university, through lack of means, before he had taken a degree, and returned to Florence, where his family habitually resided. We next hear of him as lecturing before the Florentine Academy on the site and dimensions of Dante's Inferno; and he shortly afterwards published an essay descriptive of his invention of the hydrostatical balance, which rapidly made his name known throughout Italy. His first patron was the Marchese Guidubaldo del Monte of Pesaro, a man eminent for his scientific attainments, as well as influential by his family connexions. At his request he wrote, in 1588, a treatise on the centre of gravity in solids, which obtained for him, together with the title of "the Archimedes of his time,' the honourable though not lucrative post of mathematical lecturer at the Pisan university. During the ensuing two years (1589-91) he carried on that remarkable series of experiments, by which he established the first principles of dynamical science, and by which he earned for himself the

In this

Galileo seems, at an early period of his life, to have adopted the Copernican theory of the solar system, and was deterred from avowing his opinions-as is proved by his letter to Kepler of August 4, 1597-by the fear of ridicule rather than of persecution. The appearance, in September 1604, of a new star in the constellation Serpentarius, afforded him indeed an opportunity, of which he eagerly availed himself, for making an onslaught upon the Aristotelian axiom of the incorruptibility of the heavens; but he continued to conform his public teachings in the main to Ptolemaic principles, until the discovery of a novel and potent implement of research placed at his command startling and hitherto unsuspected evidence as to the constitution and mutual relations of the heavenly bodies. Galileo was not the original inventor of the telescope.1 That

1 The word telescope, from Tλe, far, okowéw, to view, was invented by Demiscianus, an eminent Greek scholar, at the request of Prince Cesi, president of the Lyncean Academy. It was used by Galileo as early as 1612, but was not introduced into English until much later. In 1655 the word telescope was inserted in Bagwell's Mysteries of Astronomy, as a term requiring explanation, trunk or cylinder being commonly used instead.

honour must be assigned to Hans Lippershey, an obscure |
optician of Middleburg, who, on the 21st of October 1608,
offered to the states of Holland three instruments by which
the apparent size of remote objects was increased. But
here his glory ends, and that of Galileo begins. The
rumour of the new invention, which reached Venice in
April or May 1609, was sufficient to set the Italian philo-
sopher on the track; and after one night's profound
meditation on the principles of refraction, he succeeded in
producing a telescope of threefold magnifying power. Upon
this first attempt he rapidly improved, until he attained to
a power of thirty-two, and his instruments, of which he
manufactured hundreds with his own hands, were soon in
request in every part of Europe. Two lenses only-a plano-
convex anda plano-concave-were needed for the composition
of each, and this simple principle is that still employed in
the construction of opera-glasses. Galileo's direction of his
new instrument to the heavens formed an era in the history
of astronomy. Discoveries followed upon it with astound-
ing rapidity and in bewildering variety. The Sidereus
Nuncius, published at Venice in the early part of 1610,
contained the first-fruits of the new mode of investigation,
which were sufficient to startle and surprise the learned on
both sides of the Alps. The mountainous configuration of
the moon's surface was there first described, and the so-
called "phosphorescence" of the dark portion of our
satellite attributed to its true cause-namely, illumination
by sun-light reflected from the earth. All the time-worn
fables and conjectures regarding the composition of the
Milky Way were at once dissipated by the simple statement
that to the eye, reinforced by the telescope, it appeared as
a congeries of lesser stars, while the great nebula were
equally declared to be resolvable into similar elements.
But the discovery which was at once perceived to be most
important in itself, and most revolutionary in its effects,
was that of Jupiter's satellites, first seen by Galileo
January 7, 1610, and by him named Sidera Medicea, in
honour of the grand-duke of Tuscany, Cosmo II., who had
been his pupil, and was about to become his employer. An
illustration is, with the general run of mankind, more
powerful to convince than an argument; and the cogency
of the visible plea for the Copernican theory offered by the
miniature system, then for the first time disclosed to view,
was recognizable in the triumph of its advocates, as well
as in the increased acrimony of its opponents.

Quirinal Palace the telescopic wonders of the heavens to
the most eminent personages at the pontifical court. En-
couraged by the flattering reception accorded to him, he
ventured, in his Letters on the Solar Spots, printed at Rome
in 1613, to take up a more decided position towards that
doctrine on the establishment of which, as he avowed in a
letter to Belisario Vinta, secretary to the grand-duke, “all
his life and being henceforward depended." Even in the
time of Copernicus some well-meaning persons had sus-
pected a discrepancy between the new view of the solar
system and certain passages of Scripture a suspicion
strengthened by the anti-Christian inferences drawn from
it by Giordano Bruno; but the question was never formally
debated until Galileo's brilliant discoveries, enhanced by
his formidable dialectic and enthusiastic zeal, irresistibly
challenged for it the attention of the authorities. Although
he earnestly deprecated the raising of the theological issue,
and desired nothing better than permission to pursue un-
molested his physical demonstrations, it must be admitted
that, the discussion once set on foot, he threw himself into
it with characteristic impetuosity, and thus helped to pre-
cipitate a decision which it was his ardent wish to avert.
In December 1613 a Benedictine monk named Benedetto
Castelli, at that time professor of mathematics at the uni-
versity of Pisa, wrote to inform Galileo of a recent discus-
sion at the grand-ducal table, in which he had been called
upon to defend the Copernican doctrine against theological
objections. This task Castelli, who was a steady friend and
disciple of the Tuscan astronomer, seems to have discharged
with moderation and success. Galileo's answer, written,
as he said himself, currente calamo, was an exposition of a
formal theory as to the relations of physical science to Holy
Writ, still further developed in an elaborate apology ad-
dressed by him in the following year (1614) to Christina
of Lorraine, dowager grand-duchess of Tuscany.
satisfied with explaining adverse texts, he met his oppon-
ents with unwise audacity on their own ground, and endea-
voured to produce scriptural confirmation of a system which
to the ignorant many seemed an incredible paradox, and to
the scientific few was a beautiful but daring innovation.
The rising agitation on the subject which, originating pro-
bably with the sincere upholders of the integrity of Scrip-
ture, was fomented for their own purposes by the rabid
Aristotelians of the schools, was heightened rather than
allayed by these manifestoes, and on the fourth Sunday of
the following Advent found a voice in the pulpit of Santa
Maria Novella. Padre Caccini's denunciation of the new
astronomy was indeed disavowed and strongly condemned
by his superiors; nevertheless, on the 5th of February
1615, another Dominican monk named Lorini laid Galileo's
letter to Castelli before the Inquisition.

In September 1610 Galileo finally abandoned Padua for Florence. His researches with the telescope had been rewarded by the Venetian senate with the appointment for life to his professorship, at an unprecedentedly high salary. His discovery of the "Medicean Stars" was acknowledged by his nomination (July 12, 1610) as philosopher and mathematician extraordinary to the grand-duke of Tuscany. The emoluments of this office, which involved no duties save that of continuing his scientific labours, were fixed at 1000 scudi; and it was the desire of increased leisure, rather than the promptings of local patriotism, which induced him to accept an offer, the first suggestion of which had indeed come from himself. Before the close of 1610 the memorable cycle of discoveries begun in the previous year was completed by the observation of the ansated or, as it appeared to Galileo, triple form of Saturn (the ring-formation was first recognized by Huygens in 1655), of the phases of Venus, and of the spots upon the sun. Although his priority in several of these discoveries has been contested, inquiry has in each case proved favourable to his claims. In the spring of 1611 he visited Rome, and exhibited in the gardens of the

Cardinal Robert Bellarmine was at that time by far the most influential member of the Sacred College. He was a man of vast learning and upright piety, but, although personally friendly to Galileo, there is no doubt that he saw in his scientific teachings a danger to religion. The year 1615 seems, however, to have been a period of suspense. Galileo received, as the result of a conference between Cardinals Bellarmine and Del Monte, a semi-official warning to avoid theology, and limit himself to physical reasoning. "Write freely," he was told by Monsignor Dini, "but keep outside the sacristy." Unfortunately, he had already committed himself to dangerous ground, In December he repaired personally to Rome, full of confidence that the weight of his arguments and the vivacity of his eloquence could not fail to convert the entire pontifical court to his views. He was cordially received, and eagerly listened to, but his imprudent ardour served but to injure his cause. On the 24th of February 1616 the consulting theologians of the Holy Office characterized the two propositions--that the sun
