Translation of "Laomedon's" in French

One perched, Celaeno, on a rock, and lo, / thus croaked the dismal seer her prophecy of woe. / "War, too, Laomedon's twice-perjured race! / War do ye bring, our cattle stol'n and slain? / And unoffending Harpies would ye chase / forth from their old, hereditary reign?"

Céléno reste seule, et ses cris menaçants / font du haut d'un rocher entendre ces accents : / " Lâches usurpateurs de notre antique terre ! / Quoi ! pour un vil butin vous nous livrez la guerre ! "
