 Mussato classicized Latin prose in his letters and plays, suggesting he rejected traditional medieval prose metric in favour of classical Latin.He was the first, besides Lovati, to use classicizing style in poetic letters, and in his use of classical Latin, displays a founding characteristic of later humanists in his rejection of the contemporary style of Latin in favour of classical Latin.As well as letters, emulation of classical authors and style also influenced Mussato in historical writing, as he acted as chronicler in works such as "Historia Augusta" which described events such as Henry IV's invasion of Brescia.
