ISOLANI, ISIDORO de. - Dominican writer, born in Milan, probably between 1477 and 1480, and died around the middle of 1528. He successively taught in Pavia (1513), Verona (1515), Milan (1517), and Cremona (1519). In 1521-22 he was bachelor, and later regent in Bologna.
He was among the first Italian Dominicans to engage in polemics with Luther (*Revocatio Martini Lutheri augustiniani ad S. Sedem*, year, Cremona 1519). He left various and appreciated works on philosophy (*De immortalitate humani animi*, Milan 1520), hagiography, and theology. But his fame is chiefly linked to the *Summa in quatuor partes divisa de donis s. Ioseph, sponsi Beatissimae V. M.* (Pavia 1522, Avignon 1861, with French translation, Rome 1887), with which he took a leading role in spreading the cult of St. Joseph and established its theological foundations. In elegant language, abundant doctrine, and great piety, he enumerates and illustrates more than 60 gifts of the holy patriarch.
