Caelius Rhodiginus (born Lodovico Ricchieri; 1469, Rovigo–1525, Rovigo) was a Venetian writer, and professor in Greek and Latin.
His original name was Ludovico or Lodovico Celio Ricchieri. He took the name Rhodiginus from his birthplace, Rovigo.[1] He studied at Ferrara and Padua. He was a professor in Greek and Latin at Rovigo from 1491-9, and again from 1503-4.[2] He was sacked by the council of Rovigo on 26 May 1504 because of his high-handedness in dealing with the city. He subsequently taught in many places including Bologna, Vicenca, 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.[2] His pupil Julius Caesar Scaliger described him as the Varro of his age.
His principal work was the Antiquarium Lectionum in sixteen books published in 1516.[2] It was a collection of notes on the classics and general topics.[2] He also wrote commentaries on Virgil, Ovid, and Horatius Flaccus.[2]
