Adonia
From LSJ
περὶ οὐδὲν γὰρ οὕτως ὑπάρχει τῶν ἀνθρωπίνων ἔργων βεβαιότης ὡς περὶ τὰς ἐνεργείας τὰς κατ' ἀρετήν → since none of man's functions possess the quality of permanence so fully as the activities in conformity with virtue
Latin > English (Lewis & Short)
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.
