DUPIN' (Louis Ellis), a French pried, and celebrated 
eccledadical hidorian, born at Paris, in 1657. After be¬ 
ing initiated in the elements of grammar, he was placed 
under the tuition of M. Lair, reftor of the univerfity of 
Paris, and foon didinguifhed himfelf by his attachment 
to the dudy of the belles-lettres, and the fciences. Hav¬ 
ing gone through the courfes clallical learning and of 
philofophy in the college of Harcourt, he was admitted 
to the degree of mader of arts in 1672 ; on which occa¬ 
fion lie particularly recommended himfelf to notice by 
the able manner in which he performed the cudomary 
collegiate exercifes. Soon afterwards he determined on 
embracing the ecclefiadical profefiion, and to prepare 
himfelf for it diligently attended the courfe ot theologi¬ 
cal leCtures at the Sorbonne. When he had finiflied that 
courfe, he.clofely applied himfelf to the dudy of the hif- 
tory of the councils-, and the works of the Greek and 
Latin fathers. I11 1680, he took his degree of bachelor 
of the Sorbonne, in his examination for which he had the 
honour of danding in the highed rank of meritorious 
candidates ; in the fame year he was licenfed to officiate 
as a pried ; and was afterwards appointed profelfor in 
the College Royal. In 16^4 he received the bonnet of 
doctor of "the Sorbonne, and immediately afterwards em¬ 
ployed himfelf on the production ©f his grand and valu¬ 
able work entitled Bibliotheque univerjelle des Auteurs Eccle- 
fiajliques, &c. or, Kidory of Ecclefiadical Writers: con. 
raining an Account of the Authors of the feveral Books 
of the Old and New Tedaments; and the Lives and 
Writings of the Primitive Fathers, &c. This work has 
undergone a’variety of impreflions in France, Holland, 
and England, in octavo, quarto, and folio, and will always 
be confulted with great’advantage by the Undent in ec¬ 
clefiadical hidory. Having joined with thole doctors of 
the Sorbonne who fubferibed to the celebrated Cafe of 
Confcience, relative to the difputes concerning the opi¬ 
nions of Janfenius, he expofed himfelf to the refentment 
of the pope, and of the court Of France. The confe. 
quence was/that in 1703, he was deprived of his profefi.

forfh'p, and banifited to Chatellerant; whence he was 
not permitted to return to Paris before he had retraCted 
the' meafure which lie had taken ; and even then was not 
reinflated in his profefibrfhip. He met with much trou¬ 
ble, on account of the correfpondence which he held 
with Dr. Wake, archbifliop of Canterbury, relative to a 
projefb for uniting the churches of England and France- 
In the beginning of the year 1719, his papers were feized 
by order of the government, and innumerable calumnies’ 
were propagated to his prejudice; but as no charge 
could be edablifhed againd him, excepting that of great, 
candour and moderation, aqd a defire to heal the divi- 
fions in the Chridian world, his enemies were difap. 
pointed, and he was permitted to fpend his few remain, 
ing days in peace. He died at Paris in the fixty-fecond 
year of his age, deeply regretted both by his friends and 
the public in general, Befides his grand work already

DUPLE'IX (Scipio), a French hidorian, born in 1369, 
at Condom. He became known to queen Margaret of 
Navarre, who brought him to Paris in 160-3, and made 
him her mader-of-requeds. He afterwards obtained the 
pod of hidoriographer of France, and laudably employed 
many years in refearches into the ancient records of his 
country. The fruits of thefe were, his Memoirs of the 
Gauls, 4to. 1619, a work in confiderable edeem for its 
matter, though ill written. This condituted the firft 
part of his Hidory of France, of which there are two 
editions; the fil'd of five volumes folio, the fecond of 
fix volumes. The narration is brought down to the year
