This ifland was originally a part of the Spanifti empire 
in America. It was reduced under the Britilh dominion 
by Penn and Venables in 1656, and ever fince has been 
fubjeft to Great Britain. The government of it is one 
of the richeft places, next to that of Ireland, in the difpofal 
of the crown, the Handing Hilary being 3500I. per an¬ 
num, and the aflembty commonly vote as much more to 
the governor; which, with other perquifites, make it on 
the whole little lefs than io,oool. a year. This fine ifland 
isfubjeft to earthquakes and hurricanes, which have done 
it incredible damage.

JAM'BLICUS, the name of three ancient philofophers 
who lived at different periods. The firft in order of time 
was a Syrian by nation, and educated at Babylon. When 
the emperor Trajan conquered Aflyria, he was reduced 
to flavery; but afterwards recovered his liberty, and flou¬ 
riflied under the reign of the emperor Antoninus. He

was the author of a treatife, in the Greek language, enti¬ 
tled, Babylonica de Sinonidis & Rhodanis Amoribus, in iixteen 
books, tile heads of which may be feen by the curious 
reader in the ninety-fourth chapter of Photius’s Codex. 
A manufcript of the entire work was faid to be lodged in 
the library of the Efcurial; but it was deitroyed by the 
fire which confumed a confiderable part of that collection, 
in the year 1671. Leo Allatius has preferved a fragment 
of it, accompanied with his own Latin verfion, in his Se¬ 
lections from the Manufcripts of Greek Rhetoricians and 
Sophilts, printed at Rome in 1641, 8vo. 
The fecond Jamblicus, a platonic philofopher of the 
eclectic fchooi, who flouriflied towards tire beginning of 
the fourth century, was probably a defcendant from the 
preceding, and. born at Chalcis, a city of Ccelo-Syria. 
He firft ftudied under Anatolius, who prefided in a peri¬ 
patetic fchooi in Alexandria; but he foon left that fchooi, 
and became a difciple of Porphyry. He made himfelf a 
perfeCt mafter of all the myfteries of the Plotini n fy Item, 
and taught it with fuch reputation and fuccefs, that he 
Was attended by crowds of dilcipl.es, who flocked to him 
from all parts. They were attracted not fo much by his 
eloquence, in which he was greatly inferior to Porphyry, 
as they were by the fame of his probity, and the freedom 
with which he converted with them on philofophical lub- 
jeCts ; wdiile, at the fame time, he was careful to excite 
their admiration, and command their reverence, by mak¬ 
ing high pretentions to theurgical powers. He aitoniflied 
them with wonders, which he profefled to perform by 
means of an intercourfe with invifible beings. Hence he 
was called, “the mod divine and wonderful teacher.” 
His writings difcover extenfive reading; but the ftyle in 
which thay are drawm up is greatly deficient in accuracy 
and elegance. His philofophical works are alfo exceed¬ 
ingly oblcure ; neverthelels they are valuable as furnifli- 
ing us with authentic documents refpefting the Alexan¬ 
drian fchooi. The Life of Pythagoras ; An Exhortation 
to the Study of Philofophy'; three Books on Mathema¬ 
tical Learning; A Commentary upon Nicomachus’s In- 
ftitutes of Arithmetic; and A Treatife on the Myfterie3 
of the Egyptians, Chaldeans, and Aflyrians ; are all the 
writings of Jamblicus now extant. St. Jerom6 tells us, 
that he alfo wrote copious comments on the precepts of 
Pythagoras, commonly called the,Golden Verfes ; and the 
emperor Julian, who equals him to Plato himfelf, quotes 
treatife of his on the Sun, from which he has borrowed 
largely in his own treatife'on the fame fubjefh It is not 
certain where or when he died ; but from a paifage of 
Eunapius, in which he fays, that his difciple Sopater 
went, after his mafter’s death, to the court of Conltan- 
tine, we may conclude that he died before that emperor, 
and probably about the year 333. 
The third Jamblicus, who was alfo a platonic philo¬ 
fopher, was a native of Apamea in Syria, and flouriflied 
under the reign of the emperor Julian. He appears to 
have been a great favourite with that prince, who wrote 
many letters to him ; and was, probably, the perfon to 
whom Symmachus wrote, exprefling a defire of cultivat¬ 
ing his friendfhip, as that of one of the moft illuftrious 
votaries of wifdom. This philofopher is laid to have 
been poifoned under the reign of the emperor Valens. 
From the circumftances of his having been of the fame 
name and countiy with the preceding, and alfo of his hav¬ 
ing had, like him, a difciple named Sopater, it is not to 
be wondered at that the two philofophers have been con¬ 
founded together by many writers, and that the produc¬ 
tions of Jamblicus of Chalcis have been improperly at¬ 
tributed to Jamblicus of Apamea.
