GESONIAF lorus (Flor. 4.12) says that Drusus established more than fifty forts along the banks of the Rhine; and in the next sentence he says, Bonnam et Gesoniam cum pontibus junxit, classibusque firmavit.Those who think it worth the trouble to see what has been said on this corrupt passage may consult Duker's note. The reading Gesonia is very doubtful; and it is equally doubtful what the true reading is: probably some name ending in cum, so that it would be Bonnam et G . . . . cum pontibus junxit.Cluverius put Moguntiacum in place of Gesoniam cum.D'Anville is here misled by trusting, after his fashion. to resemblance of names. He saw on the map a place called Zons, as he has it, below Cologne;and it seems that the name Zonspreserves some analogy to that of Gesonia.[GESORIACUM]
