Today is the Feast of St. Lorenzo da Brindisi (1559-1619), Doctor of the Church. He's a hard one to find in English; translations have been done, but because he's not an especially widely known saint in the Anglophone world, they go out of print quickly or else end up being extremely expensive. He was born Cesare Giulio Russo, and was famous for his language skills: he knew Greek and Hebrew, and was conversationally fluent in Italian, Latin, German, Spanish, French, and a few others. Part of this was native talent, and part of it was that he used them all extensively, since he both traveled widely as a Franciscan preacher and was appointed to a number of diplomatic missions by Rome. His sermons on the Virgin Mary have always been especially highly praised. He was beatified by Pius VI, canonized by Leo XIII, and named Doctor of the Church by John XXIII.
