The Dialogue of Simon and Theophilus (Altercatio Simonis et Theophili) is a 5th-century[1] Latin Christian text giving a dialogue, akin to that of Dialogue with Trypho, between Simon, a Jew, and Theophilus, a Christian.
[2] The Altercatio is the oldest surviving Jewish-Christian dialogue preserved in Latin.
It has been attributed to, and may even be by, Cyprian.
[3] The work draws on earlier Greek and Latin traditions.
[4] Gennadius of Marseille attributes it to a monk named Evagrius.
