John I Tzimiskes
Prince Petar (r. 892-917), was entombed in the church. Christianity was spreading in his time. Prince Časlav (r. 927–960) may have added the frescoes, which are dated to the 10th century. Byzantine Emperor John I Tzimiskes (r. 969-976) recognized the Ras region as being the "focus of the "Serbian lands"", amid his annexation of the region (organizing it into a Catepanate).
