Oeneus was a king of Calydon who was the son of Portheus and Euryte and the husband of Althaea. When Dionysus came to Calydon, Oeneus accommodatingly allowed him to sleep with Althaea, and the result of this union was Deïanira (who married Heracles).
Dionysus repaid Oeneus his hospitality with the gift of viticulture, i.e. grape-growing, and according to some accounts even named wine (oinos) after him! Oeneus' name, therefore, cannot mean anything other than 'viny' (or 'winy'), and if we interpret his wife's name as 'full-flowing' (see Eur y tus, the masculine form of it), we have a well-accorded couple. There is no doubt that the English word 'wine' is related to the Greek oinos (and Latin vinum), and 'oenophile' is a rather pretentious word for someone who is, or thinks he is, a connoisseur of wine.
