RHOMPAE'A, ROMPHAE'A, and RUM'PIA (ῥομφαία). A military weapon peculiar to the Thracians (Aul. Gell. x. 25.); but whether belonging to the class of swords or of spears is a matter of doubt, though the latter seems the more probable. At all events, it was characterised by prodigious length (Liv. xxxi. 29.); and by having, like the Roman pilum, a wooden shaft of the same dimensions as the iron head affixed to it. Val. Flacc. vi. 98.
