Papal States / Papa Ioannes XVII (Pope John XVII)

Pope John XVII (Latin: Ioannes XVII) was Pope for about seven months from 16 May to 6 November 1003. He was born John Sicco, the son of another John Sicco, in the region of Rome then referred to as Biveretica. He succeeded Pope Silvester II.

John XVII was nominated to the papacy by John Crescentius, a Roman noble who held power in the city in opposition to Emperor Otto III. John XVII's successor, Pope John XVIII, was also selected by Crescentius.

John died on 6 November 1003 and was buried in the Lateran Basilica between the two doors of the principal façade. According to John the Deacon, his epitaph began by stating that "here is the tomb of the supreme John, who is said to be Pope, for so he was called."
