Dictionary of Greek and Roman Geography/Baphyras
BAPHYRAS, or BA′PHYRUS (Βαφύρας), a small river of Macedonia, flowing by Dium through marshes into the sea. It was celebrated for the excellence of its τευθίδες, or cuttle-fish. (Liv. xliv. 6; Athen. vii. p. 326, d.; Lycophr. 274.) Pausanias (ix. 30. § 8) relates that this was the same river as the Helicon, which, after flowing 75 stadia above ground, has then a subterraneous course of 22 stadia, and on its reappearance is navigable under the name of Baphyras. (Leake, Northern Greece, vol. iii. p. 411.)
