Peter of Pisa

Peter of Pisa (744–799 AD), also known as Petrus Grammaticus, was an Italian grammarian, deacon, and poet of the Early Middle Ages. Following Charlemagne's conquest of the Lombard Kingdom in 776, Peter was summoned to the Carolingian court, where he taught Latin to Charlemagne. His poetry offers a personal glimpse into the inner circle of Charlemagne's court, and his grammar texts illustrate the changes in Latin education during that period. As Latin spread with Christianity, the need for accessible teaching materials grew, especially for those whose native languages differed from Latin. Peter's grammatical works, which included questioning statements about word classes and unique applications of logic, became influential. He also engaged in "coterie poetry" with other intellectuals at court, using inside jokes and nicknames. Peter returned to Italy around 790 and died no later than 799.
