Lewis & Short

dis-sŏno, āre, v. n., to disagree in sound, to be dissonant, opp. consono (very rare; not ante-Aug.).

  1. I. Lit.: dissonantes loci, that produce discordant sounds, Vitr. 5, 8, 1.
  2. II. Trop., to disagree, to differ: an universa hujus temporis culturae respondeant, an aliqua dissonent, Col. 1, 1, 3: a veritate, Amm. 22, 15, 6: praeceptis historiae, id. 26, 1, 1; Ambros. in Luc. 6, 44. (But in Quint. 8, 6, 36, the right reading is dissentio.)
