made fun of the more conservative schoolmen with whom he was

brought in contact察that he heard察while on a visit to Venice

that a Dutch spectacle´maker had invented an instrument which was

said to represent distant objects nearer than they usually

appeared。  This was in 1609察when he察at the age of fifty´five察was

the idol of scientific men察and was in the enjoyment of an ample

revenue察giving only sixty half´hours in the year to lectures察and

allowed time to prosecute his studies in that ;sweet solitariness;

which all true scholars prize察and without which few great

attainments are made。  The rumor of the invention excited in his

mind the intensest interest。  He sought for the explanation of the

fact in the doctrine of refraction。  He meditated day and night。

At last he himself constructed an instrumenta leaden organ pipe

with two spectacle glasses察both plain on one side察while one of

them had its opposite side convex察and the other its second side

concave。



This crude little instrument察which magnified but three times察he

carries in triumph back to Venice。  It is regarded as a scientific

toy察yet everybody wishes to see an instrument by which the human

eye indefinitely multiplies its power。  The Doge is delighted察and

the Senate is anxious to secure so great a curiosity。  He makes a

present of it to the Senate察after he has spent a month in showing

it round to the principal people of that wealthy city察and he is

rewarded for his ingenuity with an increase of his salary察at

Padua察to one thousand florins察and is made professor for life。



He now only thinks of making discoveries in the heavens察but his

instrument is too small。  He makes another and larger telescope

which magnifies eight times察and then another which magnifies

thirty times察and points it to the moon。  And how indescribable his

satisfaction察for he sees what no mortal had ever before seen

ranges of mountains察deep hollows察and various inequalities  These

discoveries察it would seem察are not favorably received by the

Aristotelians察however察he continues his labors察and points his

telescope to the planets and fixed starsbut the magnitude of the

latter remain the same察while the planets appear with disks like

the moon。  Then he directs his observations to the Pleiades察and

counts forty stars in the cluster察when only six were visible to

the naked eye察in the Milky Way he descries crowds of minute stars。



Having now reached the limit of discovery with his present

instrument察he makes another of still greater power察and points it

to the planet Jupiter。  On the 7th of January察1610察he observes

three little stars near the body of the planet察all in a straight

line and parallel to the ecliptic察two on the east and one on the

west of Jupiter。  On the next observation he finds that they have

changed places察and are all on the west of Jupiter察and the next

time he observes them they have changed again。  He also discovers

that there are four of these little stars revolving round the

planet。  What is the explanation of this singular phenomenon拭 They

cannot be fixed stars察or planets察they must then be moons。

Jupiter is attended with satellites like the earth察but has four

instead of one  The importance of this last discovery was of

supreme value察for it confirmed the heliocentric theory。  Old

Kepler is filled with agitations of joy察all the friends of Galileo

extol his genius察his fame spreads far and near察he is regarded as

the ablest scientific man in Europe。



His enemies are now dismayed and perplexed。  The principal

professor of philosophy at Padua would not even look through the

wonderful instrument。  Sissi of Florence ridicules the discovery。

;As察─said he察 there are only seven apertures of the headtwo

eyes察two ears察two nostrils察and one mouthand as there are only

seven days in the week and seven metals察how can there be seven

planets拭



But science察discarded by the schools察fortunately finds a refuge

among princes。  Cosimo de' Medici prefers the testimony of his

senses to the voice of authority。  He observes the new satellites

with Galileo at Pisa察makes him a present of one thousand florins

and gives him a mere nominal officethat of lecturing

occasionally to princes察on a salary of one thousand florins for

life。  He is now the chosen companion of the great察and the

admiration of Italy。  He has rendered an immense service to

astronomy。  ;His discovery of the satellites of Jupiter察─says

Herschel察 gave the holding turn to the opinion of mankind

respecting the Copernican system察and pointed out a connection

between speculative astronomy and practical utility。;



But this did not complete the catalogue of his discoveries。  In

1610 he perceived that Saturn appeared to be triple察and excited

the curiosity of astronomers by the publication of his first

;Enigma察─Altissimam planetam tergeminam observavi。  He could not

then perceive the rings察the planet seemed through his telescope to

have the form of three concentric O's。  Soon after察in examining

Venus察he saw her in the form of a crescent此Cynthiae figuras

aemulatur mater amorum察 Venus rivals the phases of the moon。;



At last he discovers the spots upon the sun's disk察and that they

all revolve with the sun察and therefore that the sun has a

revolution in about twenty´eight days察and may be moving on in a

larger circle察with all its attendant planets察around some distant

centre。



Galileo has now attained the highest object of his ambition。  He is

at the head察confessedly察of all the scientific men of Europe。  He

has an ample revenue察he is independent察and has perfect leisure。

Even the Pope is gracious to him when he makes a visit to Rome

while cardinals察princes察and ambassadors rival one another in

bestowing upon him attention and honors。



But there is no height of fortune from which a man may not fall

and it is usually the proud察the ostentatious察and the contemptuous

who do fall察since they create envy察and are apt to make social

mistakes。  Galileo continued to exasperate his enemies by his

arrogance and sarcasms。  ;They refused to be dragged at his

chariot´wheels。;  ;The Aristotelian professors察─says Brewster

;the temporizing Jesuits察the political churchmen察and that timid

but respectable body who at all times dread innovation察whether it

be in legislation or science察entered into an alliance against the

philosophical tyrant who threatened them with the penalties of

knowledge。;  The church dignitaries were especially hostile察since

they thought the tendency of Galileo's investigations was to

undermine the Bible。  Flanked by the logic of the schools and the

popular interpretation of Scripture察and backed by the civil power

they were eager for war。  Galileo wrote a letter to his friend the

Abbe Castelli察the object of which was ;to prove that the

Scriptures were not intended to teach science and philosophy察─but

to point out the way of salvation。  He was indiscreet enough to

write a longer letter of seventy pages察quoting the Fathers in

support of his views察and attempting to show that Nature and

Scripture could not speak a different language。  It was this

reasoning which irritated the dignitaries of the Church more than

his discoveries察since it is plain that the literal language of

Scripture upholds the doctrine that the sun revolves around the

earth。  He was wrong or foolish in trying to harmonize revelation

and science。  He should have advanced his truths of science and

left them to take care of themselves。  He should not have meddled

with the dogmas of his enemies此not that he was wrong in doing so

but it was not politic or wise察and he was not called upon to

harmonize Scripture with science。



So his enemies busily employed themselves in collecting evidence

against him。  They laid their complaints before the Inquisition of

Rome察and on the occasion of paying a visit to that city察he was

summoned before that tribunal which has been the shame and the

reproach of the Catholic Church。  It was a tribunal utterly

incompetent to sit upon his case察since it was ignorant of science。

In 1615 it was decreed that Galileo should renounce his obnoxious

doctrines察and pledge himself neither to defend nor publish them in

future。  And Galileo accordingly察in dread of prison察appeared

before Cardinal Bellarmine and declared that he would renounce the

doctrines he had defended。  This cardinal was not an ignorant man。

He was the greatest theologian of the Catholic Church察but his

bitterness and rancor in reference to the new doctrines were as

marked as his scholastic learning。  The Pope察supposing that

Galileo would adhere to his promise察was gracious and kind。



But the philosopher could not resist the temptation of ridiculing

the advocates of the old system。  He called them ;paper

philosophers。;  In private he made a mockery of his persecutors。
