Perpetua of Carthage d. 203 ADPassion of Perpetua and Felicity 7.1–4
A few days later, while we were all praying, suddenly in the middle of the prayer a word came to me, and I named Dinocrates ... And I knew at once that I was worthy, and ought to ask for him. And I began to pray much for him, and to groan to the Lord. That very night this was shown me: I see Dinocrates coming out of a dark place, where there were many others, very hot and thirsty, with a dirty face and pale color.
