MENCKE (John Burchard), son to the preceding. After his studies he travelled into England and Holland; and upon his return was appointed professor of history at Leipzig in 1699. He gained great reputation by his lectures as well as his writings. He died in 1732, aged 38. He wrote many pieces. His De Charlataneria eruditorum declamationes duæ, is an excellent satire, designed to expose the artifices used by false scholars to raise themselves a name. As he named and pointed at certain persons, it exasperated them, and they procured his book to be seized; but it spread, and editions of it were multiplied. He likewise published Méthode pour étudier l'Histoire, avec un catalogue des principaux historiens, &c. He made a great many additions to Mr Lenglet's book, especially with regard to the German historians.
