Tirissa
Tirissa (Geogr. Rav. 4.6), called by Arrian Τετρισίας (Per. P. Eux. p. 24), and in the Tab. Peut. Trissa; a fortified place on the promontory of Tirizis. From its situation on this bold headland it was sometimes called simply Ἄκρα (Steph. B. sub voce p. 53; Hierocl. p. 637), and hence at present Ekerne or Kavarna.
