As a starting point, the paper asserts that there was no geographic region
called Diokletia Hvostanska (Diokletia of Hvosno), which is mentioned in
just two sources ? one from the 15th and another from the 18th century. The
root of this misconception is an erroneous reading of a section in
Teodosije?s Vita of St. Peter of Korisa, which recounts that the saint was
born in the area of Hvosno in Diokletia. Starting from the fact that Hvosno
was in Diokletia, i.e., Duklja or Diokleia, only when this historical region
was ruled by King Vukan, son of the Serbian grand zupan Stefan Nemanja ? in
the last decade of the 12th and the very beginning of the 13th century ? the
birth of Peter of Korisa is dated to this period. Accordingly, his life and
miracles would belong to the 13th century. Based on an in-depth analysis of
the most important details about the death of St. Peter of Korisa and the
beginnings of his cult ? the chronological distance of Teodosije?s Vita of
St. Peter of Korisa from the saint?s death, the transfer of some of his
relics to Constantinople, the time of writing of the earliest service
dedicated to him, and the earliest layer of frescoes at the hermitage of St.
Peter of Korisa ? I propose that the saint died no later than c. 1270 and
that Teodosije composed his service and vita in the last decade of the 13th
century. In the time separating these two events, the saint?s relics were
revealed as incorruptible, and he began to be venerated.
