πυκός
From LSJ
Τὸ νικᾶν αὐτὸν αὑτὸν πασῶν νικῶν πρώτη τε καὶ ἀρίστη. Τὸ δὲ ἡττᾶσθαι αὐτὸν ὑφ' ἑαυτοῦ πάντων αἴσχιστόν τε ἅμα καὶ κάκιστον. → Τo conquer yourself is the first and best victory of all, while to be conquered by yourself is of all the most shameful as well as evil
German (Pape)
[Seite 816] alte Form statt πυκνός, wovon sich nur bei Dichtern das adverbial gebrauchte πύκα erhalten hat. Von der lakonischen Form πουκός hat Simmias ov. 20 (XV, 27) den superl. πουκότατος.
