 Later humanists, such as Petrarch and Dante are argued to be indebted to the works of the early Northern Italian humanists such as Lovati and Mussato.Mussato was influenced by his teacher and contemporary, Lovato Lovati, a figure also associated with Northern Italian humanism.Lovati was one of the first to demonstrate "proto-humanism" and is known for the discovery of Seneca's plays as well as familiarity with ancient lyric poets such as Catullus, Tibullus, and Propertius.
