GESDAO or GESDAONE, as it appears in the oblique case in the Itin. Jerusalem; Gascido in the Table, which D'Anville read Gadao. The Jerusalem Itin. places it on a road from Brigantio ( Briançon) to Susa:and it makes 10 M. P. from Brigantium to Gesdao, and 9 from Gesdao to Mutatio ad Marte. The Antonine Itin. makes 18 M. P. from Brigantio to Ad Martis, and omits Gesdao. The Table makes 6 M. P. from Brigantio to Alpis Cottia ( Mont Genèvre), and then 5 M. P. to Gascido, and 8 from Gascido to Ad Martis. All these numbers agree pretty well, and by following the road from Brianonthe position thus determined seems to be Cesanoor Sezano.
