De Pomis was a rabbi and physician. "... on account of the edict of Pius IV forbidding Jewish physicians to attend Christians (1555), he moved from town to town in Italy before he settled in 1569 in Venice, where he published the greater part of his works. Pius IV (1559–65) gave him permission to attend Christians, a concession revoked by Pius V (1565–72) and later restored by Pope Sixtus V (1585–90). In his booklet De Medico Hebraeo Enarratio Apologica (Venice, 1588) David de’ Pomis refutes the charges brought against Jews and Jewish physicians in particular by a bull of 1581 by Gregory XIII (1572–85). He stresses that according to the Bible and Talmud a Jewish physician must give help to every sufferer, and cites numerous instances of Jewish doctors who had distinguished themselves by their work and their loyalty. The volume ends with a selection of talmudic rules translated into Latin in order to prove that the Talmud should not be despised" (https://www.jewishvirtuallibrary.org/pomi-s-de-x0027, accessed 9-2021).
