The headword is accusative plural of the rare noun qea/mwn, evidently quoted from somewhere (probably a Christian theological text, e.g. John of Damascus or Maximus the Confessor).
The Ionic form qeh/monas occurs in the Greek Anthology 16.365.3.

[2] cf. Hesychius theta161 (s.v. qe/ama) and, according to Adler, the Ambrosian Lexicon (72-3).
