 Riccio relates that he was ordered by Emperor Maximilian to prepare a Latin translation of the "Talmud".All that has come down of it are the translations of the tractates "Berakot", "Sanhedrin", and "Makkot" (Augsburg, 1519), which are the earliest Latin renderings of the "Mishnah" known to bibliographers.The most important of his other works is "De Cælesti Agricultura", a large religio-philosophical work in four parts, dedicated to Emperor Charles V and to his brother Ferdinand (Augsburg, 1541; 2d ed., Basel, 1597).
