Adonia
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

Ădōnĭa: ōrum, n., τὰ Ἀδώνια,
I the festival of Adonis. It returned annually in June, about the time of the summer solstice, and was celebrated (even in Rome; cf. Manso, Essays on Myth.) with alternate lamentations and exultations, on account of the death of Adonis, Amm. 22, 9. This festival was a symbol of the dying and reviving again of nature; cf. Hier. ad Ez. 8; Creuz. Symb. 2, 86; Böttig. Sab. 1, 261 sq.
