The Nuttall Encyclopedia
One of the books of the Apocrypha, ascribed to Jesus, the son of Sirach, admitted to the sacred canon by the Council of Trent, though excluded by the Jews. It contains a body of wise maxims, in imitation, as regards matter as well as form, of the Proverbs of Solomon, and an appendix on the men who were the disciples of wisdom. Its general aim, as has been said, is "to represent wisdom as the source of all virtue and blessedness, and by warnings, admonitions, and promises to encourage in the pursuit of it." It was originally written in Hebrew, but is now extant only in a Greek translation executed in Egypt, professedly by the author's grandson.
