De vita et moribus philosophorum information

De vita et moribus philosophorum ('Lives and Manners of the Philosophers')^[1] is an anonymous Latin biographical dictionary of 132 ancient Greek and Roman philosophers and other luminaries from Thales of Miletus in the 6th century BC to Priscian in the 6th century AD.^[2] It was written in about 1317–1320 and draws heavily on Henricus Aristippus's Latin translation of the Greek Lives and Opinions of Eminent Philosophers of Diogenes Laertius. It was formerly attributed to Walter Burley, but is now recognized as anonymous. Its author may be known as "Pseudo-Walter Burley".^[3]

There are over 150 manuscript copies of De vita et moribus philosophorum, mostly from France and Italy. It was a popular early printed book, going through 30 editions by 1530. A Spanish translation was made in the early 15th century, an Italian translation by 1475 and three in Polish by the early 16th century.^[1] Two German translations, one by Hans Lobenzweig [de] and another by Anton Sorg, had appeared by 1490.^[1][4]

De vita et moribus philosophorum was used as a source by Giovanni Colonna in his De viris illustribus begun in 1329.^[5]
