GUEVA'RA (Antony de), hiftoriographer to the 
emperor Charles V. born in the province of Alava in 
Spain. He was brought up at court, but after the 
death of queen Ifabella of Caftile he became a fran- 
cifcan monk, and obtained feveral honourable employ¬ 
ments in the order. His eloquence caufed him (o be ap¬ 
pointed preacher, as well as hiftoriographer, to Charles V. 
and he acquired a great reputation by his pulpit ha¬ 
rangues. He publilhed a work, entitled, The Dial of 
Princes, or Marcus Aurelius, pretending to be a hif- 
tory of that emperor and Fauftina his wife, drawn from 
ancient authorities, but entirely fictitious. The book 
was, however, extremely popular, and feveral French 
and Italian tranflations were made of it. He alfo wrote 
letters, called Golden Epiftles, and feveral other works. 
He was nominated to the bilhopric of Guadix in the 
kingdom of Grenada, and afterwards to that of Modo- 
nedo in Gallicia. He died in 1544.

time to literary purfuits. He left behind him, Com¬ 
mentaries on the Pfalms, and on the Prophet Habukkuk, 
and a treatife in defence of the authenticity of the Vul¬ 
gate tranflation of the Bible: a topic which the decree 
of the council of Trent occafioned to be much dif- 
cufled, both by catholics and proteftants.

GUGLIEL'MINI (Dominic), an eminent Italian en¬ 
gineer, born at Bologna in 1655. His favourite ftudies 
were the mathematics and medicine ; in the former of 
which he had for tutor the celebrated M. Germ. M011- 
tanari, and in the latter, the illuftrious Malpighi. In 
1678 he was admitted to the degree of dodtor of medi¬ 
cine, by the univerfity of Bologna. Upon the appear¬ 
ance of the remarkable comet in the years 1680 and 
1681, he publilhed a treatife, De Cometarum datura d? 
Vol. IX. No. 567. 
G U H 77 
Orlu, &c. 1681, in which he propofed a new fyftem on 
the fubjedl, which he thought would ferve to explain 
all the phenpmena of thofe heavenly bodies ; but it did 
not meet with the approbation of the feientific world. 
His next aftronomical treatife, containing remarks on 
the foliar eclipfe which took place on the 12th of July, 
1684, and which he publilhed. in Latin, at Bologna in 
the fame year, reflected greater credit on hisknowledge 
and accuracy of obfervation. Soon afterwards the le- 
nate of Bologna appointed him principal profefior of 
mathematics in the univerfity of that city, and in 1686 
made him intendant-general of the rivers of the Bo- 
lognefe. In 1690, he publilhed the firft part, and in 
the following year the fecond part, of an excellent hy-- 
droftatical treatife, entitled, AquarumFlucntium Menfura, 
novo Mcthodo inquijita. In 1697 he publilhed his grand 
phyfieo-mathematical-treatife on the-nature of rivers, 
entitled, Della Natura de Fiumi, which raifed his reputa¬ 
tion to the higheft pitch for feientific knowledge, inge¬ 
nuity, and judgment, in hydraulics. Montucla com¬ 
mends it in warm terms, and fays that it ought to be 
' carefully ftudied by every perfon who would with to 
become thoroughly mailer of this branch of fcience. 
The reputation which Guglielmini acquired by this 
performance, occafioned his being employed by the 
dukes of Mantua, of Parma and Modena, the grand 
duke of Tufcany, pope Clement XI. the republics of 
Venice and Lucca, &c. in the invention and conftruc- 
tion of the neceflary hydraulic works in their refpeCtive^ 
territories. In 1698 he was induced by the republic of 
Venice to accept of the mathematical chair in the uni- 
veffity of Padua ; but the fenate of Bologna decreed 
that he Ihould Hill retain, notvvithftanding his new em¬ 
ployment, the title of profelfor in their univerfity, and 
the emoluments annexed to it. In 1702, he exchanged 
his mathematical chair at Padua for the more lucrative 
one of medicine ; after which he publilhed different 
treatifes on medical and chemical fubjeCts. He died at 
Padua in 1710, in the fifty-fifth year of his age. He 
had been admitted a member of the academy of lciences 
at Paris in 1696, and was alfo correfponding member of 
the academies of Berlin and Vienna, and of the royal 
fociety at London. The bed edition of his treatife on 
the nature of rivers was publilhed at Bologna, in 1756, 
with the notes of Manfredi ; and the whole of liis 
works were printed in a collective form at Geneva, in 
i.719, in 2 vols. 4to.
