Catacomb of Trasone

The Catacomb of Trasone is a catacomb on the left side of the ancient via Salaria, at its junction with via Yser, in the modern-day Parioli quarter of Rome. Begun in the 3rd century, is named after Trason or Thrason, a rich Christian Roman citizen under Diocletian and the owner of the land in which it was dug - he is named in a martyrdom account of Susanna of Rome. Ancient sources also call it Coemeterium Thrasonis ad s. Saturninum (the cemetery of Thrason at [the basilica of] saint Saturninus in memory of the main martyr buried there, the remains of whose above-ground basilica were still visible late in the 16th century.
