Tamarus
Tamarus (Tamaro), a river of Samnium, which falls into the Calor (Calore), about 5 miles above Beneventum. Its name is known only from the Itinerary of Antoninus, which places a station super Tamarum fluvium
on the road from Bovianum to Equus Tuticus. (Itin. Ant. p. 103.) The line of this road is not very clear, but the modern name of the Tamaro leaves no doubt of the river meant. It rises in the mountains near Saepinum, only a few miles from Bovianum, and flows with a general direction from N. to S. till it joins the Calor as above indicated.
