St. Cyprian of Carthage
c. 210–258
St. Cyprian of Carthage, who had been Stephen's opponent in the matter, wrote of him warmly, and Cyprian's deacon Pontius calls him a good and peaceable bishop.
From there he wrote to the African bishops that Sixtus of Rome had been taken in a cemetery on the sixth of August, 258, and beheaded, and that the persecution would come for him next.
