RANIERO GIORDANI da PISA. - Dominican theologian, born at Rivalto, died at Pisa in 1348. He studied at Paris and taught at Pisa and in other convents of his Order.
A diligent scholar and a good connoisseur of St. Thomas, he wrote the Pantheologia, which is the oldest dictionary of theology. The subject matter is presented in alphabetical order; compiled from various writers, it nevertheless possesses doctrinal unity through the author’s intelligent elaboration. The work, begun in 1331, is clearly inspired by Thomism; the influence of St. Bonaventure and Alexander of Hales is likewise noteworthy. It soon enjoyed wide circulation; the first known edition is that of Nuremberg of 1474, under the title: Summa et nucleus theologiae, followed by many others (Mainz 1477, Nuremberg 1486, Cologne 1486, Lyons 1519, etc.). Two short treatises are also attributed to him: De fortuna and De sortibus.
