Chapel of the Finding of the Cross
"Inventio sanctae crucis dicitur, quia tall die sancta crux inventa fuisse refertur. Nam et antea fuit inventa a Seth, filio Adam, in terrestri paradiso, sicut infra narratur, a Salomone in Libano, a regina Saba in Salomonis templo, a Judaeis in aqua piscinae, hodie ab Helena in morte Calvarie". (Jacopo da Varagine, Legenda Aurea, LXVIII)
Descending further – and this is the lowest point of the entire church – one reaches the rock-cut Chapel of the Finding of the Cross. The traditional spot of the discovery of the relics is set off by railings. Finding of The True Cross
The walls preserve faint traces of 12th century frescoes, while on the ceiling tool marks can be seen on blocks from the ancient stone quarry. The plaster on the walls, made from a hydraulic material rich in ash commonly used at the time of Christ, is evidence that this underground area was at that time used as a cistern.
