Ancient Geography, a town of Lower Egypt, on the west side of the branch of the Nile, called Thermuthiacus; towards the mouth called Ophium Sebennyticum: in this town stood an oracle of Latona (Strabo, Herodotus). Ptolemy places Butus in the Nomos Phthothenes: it is also called Buto, -us, (Herodotus, Stephanus). It had temples of Apollo and Diana, but the largest was that of Latona, where the oracle stood.
