Lewis & Short

Leuctra, ōrum, n. (Leuctrae, ārum. f., Sol. 7), = Λεῦκτρα.

  1. I. A small town in Bæotia, where Epaminondas defeated the Spartans, now the village of Leuca, with the ruins of Eremo-Castro (cf. Mann. Griechenland, p. 238), Cic. Tusc. 1, 46, 110; id. Off. 1, 18, 61: Lacedaemoniorum mala pugna in Leuctris, id. Div. 2, 25, 54.
    Hence,
    1. B. Leuctrĭcus, a, um, adj., of or belonging to Leuctra, Leuctrian: pugna, Cic. Tusc. 1, 46, 110; v. supra: calamitas, id. Div. 1, 34, 74; id. Off. 2, 7 fin.
      Cicero jestingly gives to the fray in which Milo killed Clodius the name of Leuctrica pugna (because Rome was thereby delivered from the yoke of Clodius, as Greece had been from that of the Spartans by the battle of Leuctra), Att. 6, 1, 26.
  2. II. A small town in Laconica, now Leftro, Plin. 4, 5, 8, § 16.
