Chronicon Venetum et Gradense

The Chronicon Venetum et Gradense, formerly known as the Chronicon Sagornini, is a Venetian chronicle compiled by John the Deacon in ca. 1008. It is the oldest chronicle of the Republic of Venice.[1] John was the chaplain and perhaps a relative of Venetian Doge Pietro II Orseolo (r. 991–1009).[1] The first part, dealing with early history, is lacking, only later becoming more accurate, and in the time of John himself deemed particularly valuable.[1] It details the reign of Pietro II.[1]
