Lombard language
Bonvesin da la Riva (; sometimes Italianized in spelling Bonvesino or Buonvicino; 1240 – c. 1313) was a well-to-do Milanese lay member of the "Ordine degli Umiliati" (literally, "Order of the Humble Ones"), a teacher of (Latin) grammar and a notable Lombard poet and writer of the 13th century, giving one of the first known examples of the written Lombard language. He is often described as the "father" of the Lombard language.
