Caelius Rhodiginus (born Lodovico Ricchieri; 1469, Rovigo–1525, Rovigo) was a Venetian writer, and professor in Greek and Latin.
[3] He subsequently taught in many places including Bologna, Vicenza, Padua, and Ferrara.
[2] In 1515, he became the chair of Greek at Milan; he returned to Rovigo in 1523, and died two years later.
His principal work was the Antiquarum Lectionum in sixteen books published in 1516 in Venice at the Aldine Press.
Rhodiginus continued to collect materials towards producing a new edition, and the book was posthumously expanded to thirty books and published under the editorship of his nephew Camillo Ricchieri and G. M. Goretti in 1542 at Basle.
