great talents were displayed at fo early a period, that hav¬ 
ing (ludicd at Frankfort, and acquired under La Croze 
a knowledge of theology and of the Coptic language, he 
was admitted among the royal candidates; and at the 
king’s expence made a literary tour through Germany, 
Holland, England, and France. During this tour he had 
an opportunity of improving himfelf in the Coptic, and 
particularly at Leyden, Oxford, and Paris, where he exa¬ 
mined the different Coptic works preferved in the public 
libraries. In the year 177.0 he was appointed profeffor of 
philofophy, and preacher to the reformed congregation of 
Frankfort on the Oder; in 1727, public profeffor of theo¬ 
logy ; and afterwards member of the Academy of Scien¬ 
ces at Berlin. He died in the month of September, 1757. 
Jabloniky was a man of a very amiable character, and 
poffeffed an extenlive knowledge of theology and of the 
Coptic language, as evidently appears Ky his Pantheon 
JEgyptiacum. He was much efteemed for his friendly dif- 
pofition, Jove of truth, fincere piety, attention to his du¬ 
ties, mildnefs, and other virtues. His greateft fault was, 
that he had an almoft infuperable averiion to the publi¬ 
cation of his works; and even his Pantheon might never 
perhaps have appeared, had he not in a manner been 
compelled to commit it to the prefs. Had not this un- 
willingnefs to publifii been fo ftrong a feature in his cha¬ 
racter, the Coptic and biblical literature might have been 
confiderably benefited, He left, however, a great many 
theological and other works, the principal of which are 
the following: 1. Exercitationes in Hiftoriam Theolo¬ 
gian! de NelJorianiftno, Berol. 1724, 8vo 3. Rhempha 
./Egyptiorum Deus ab Ifraelitis in Deferto cultus, Frank.
