From the additional notes to Psalm 105 in The Treasury of David, by Charles Spurgeon.
The following entry about Folengius' life seems to have been translated from another language (his books were on the Index of books that Catholics were prohibited from reading for a time):
Jean Baptist F O L E N G I O
entered into a Benedictine monastery in his native city,
where his talents and industry obtained for him a high re
putation for proficiency in literature and sacred criticism,
while the excellence of his disposition rendered him an
object of general esteem. He was selected to fill the most
important and distinguished stations in his order, and he
was afterwards chosen by Pope Paul IV. as visitor of the
Benedictine foundations in Spain. When he had per
formed this task, he returned to his native country,
and devoted himself almost wholly to theological studies,
in the course of which he conceived the hopeless project
of uniting Catholics and Protestants in one communion.
After a life spent in the service of his fellow creatures, he
died in 1559, in his seventieth year. He left behind him
many theological writings, of which the principal were "Com
mentaries upon the Epistles of St. James, St. Peter, and
the first Epistle of St. John," published in 1551, in 8vo;
also a "Commentary upon the Psalms." These works
must have had more than common merit in respect to libe
rality of sentiment, as they were prohibited by his church.
His "Commentary on the Psalms" indeed was reprinted
in 1585, but revised and abridged. Dupin says that he
"writes purely and nobly," and Thuanus had reason to say,
"that no man will ever repent the reading of his Commentaries."
