Carantonus
Carantonus a river of Gallia, which flowed through the territory of the Santones:-- Santonico refluus non ipse Carantonus aestu.
Auson. Mosell. 5.463.
Ptolemy (2.7) and Marcianus (p. 47) call it Canentelus, or Canentellus, if it be the same stream, which may be doubted. The name is enough to show that the Carantonus of Ausonius is the Charente, for the names are the same. Ptolemy's Canentelus, according to his geography, is certainly not the Charente, but north of it.
