Attested: Leucumagna 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.
