Apollo
As sun-god and god of light, Apollo was also known by the epithets Aegletes (/@'gli:ti:z/ @-GLEE-teez; Aigletes, Aigletes, from aigle, "light of the sun"), Helius (/'hi:li@s/ HEE-lee-@s; Elios, Helios, literally "sun"), Phanaeus (/f@'ni:@s/ f@-NEE-@s; Phanaios, Phanaios, literally "giving or bringing light"), and Lyceus (/laI'si:@s/ ly-SEE-@s; Lukeios, Lykeios, from Proto-Greek *luke, "light"). The meaning of the epithet "Lyceus" later became associated with Apollo's mother Leto, who was the patron goddess of Lycia (Lukia) and who was identified with the wolf (lukos), earning him the epithets Lycegenes (/laI'sedZ@ni:z/ ly-SEJ-@-neez; Lukegenes, Lukegenes, literally "born of a wolf" or "born of Lycia") and Lycoctonus (/laI'kakt@n@s/ ly-KOK-t@-n@s; Lukoktonos, Lykoktonos, from lukos, "wolf", and kteinein, "to kill"). As god of the sun, Apollo was called Sol (/'sal/ SOL, literally "sun" in Latin) by the Romans.
