AttestedLeucumagna or Leucomag~o or Leucumagno at position 45 in the Ravenna Cosmography

Where:  Probably Portsmouth Harbour, around SU6103.

Name origin:  About Leuco-, see here, referring to an open space, plus magnus ‘large’.

Notes:  Ptolemy 2,3,33 described his Μεγας λιμην ‘great harbour’ as lying north of the Isle of Wight, for which Rivet & Smith suggested the whole Solent.  However, that does not really qualify as a harbour, though it is surrounded by inlets where small ships can moor, of which the largest is Portsmouth Harbour.  Portchester Castle, deep inside, might be the Notitia Dignitatum's Portum Adurni.
