Peter of Zittau (Czech: Petr Žitavský; c. 1275–1339) was a Bohemian churchman and historian. Born in Zittau, he entered the Cistercian monastery of Aula Regia (Zbraslav), founded by Wenceslaus II in 1292, and became the monastery's official historian.[1] He is the primary author of the Chronicon Aulae Regiae. Esteemed by his colleagues, in 1316 Peter was elected the second abbot of Aula Regia.[1][2] In this capacity he took part in the election of King John and staunchly opposed Henry of Carinthia.[1] He later grew disenchanted with John, but wrote a lengthy lament for the passing of his wife, Elizabeth, the "true heiress of Bohemia" (vera heres Boemiae), in 1330.[3]
