“The Gospel was sung from the ambo (ambon), a pulpit generally halfway down the church, from which it could be best heard by every one (Cabrol, Dict. d’archéol. chrét. et de liturgie, Paris, 1907, s.v. “Ambon”, I, 1330-47). Often there were two ambos: one for the other lessons, on the left (looking from the altar); the other, for the Gospel, on the right. From here the deacon faced south, as the “Ordo Rom. II” says (Mabillon, Musæum italic., II, 46), noting that the men generally gather there. Later, when the ambo had disappeared, the deacon turned to the north. Micrologus (De missa, ix) notices this and explains it as an imitation of the celebrant’s position at the altar at low Mass — one of the ways in which that service has reacted on to high Mass. The Byzantine Church still commands the deacon to sing the Gospel from the ambo (e.g. Brightman, op. cit., 372), though with them, too, it has generally become only a theoretical place in the middle of the floor.”
