The Cenacle (from Latin "dining room", later spelt coenaculum and semantically drifting towards "upper room"), also known as the "Upper Room", is a room in Jerusalem traditionally held to be the site of the Last Supper. The word is a derivative of the Latin word cēnō, which means "I dine". The Gospel of Mark employs the Ancient Greek: ἀνάγαιον, anagaion, (Mark 14:15), whereas the Acts of the Apostles uses Ancient Greek: ὑπερῷον, hyperōion (Acts 1:13), both with the meaning "upper room". The language in Acts suggests that the apostles used the Upper Room as a temporary residence (Ancient Greek: οὗ ἦσαν καταμένοντες, hou ēsan katamenontes), although the Jamieson-Fausset-Brown Bible Commentary disagrees, preferring to see the room as a place were they were "not lodged, but had for their place of rendezvous".
