Tamnum
Tamnum in Gallia, is placed by the Itineraries on a road from Burdigala (Bordeaux) to Mediolanum Santonum (Saintes); but in the Table the name is written Lamnum. The distance from Blavia or Blavium (Blaye) to Tamnum is xvi. in the Itins.; but the distance xxii. in the Table is nearer the truth, if Tallemont or Talmon is the site of Tamnum. Talmon is below Blaye on the right bank of the Gironde.
