Although not mentioned in any existing literature, he is depicted on ancient Greek vase paintings. A surviving example on a red-figure pyxis from the late 5th century BC shows Hedylogos alongside his brother Pothos drawing the chariot of Aphrodite.
To the Romans he was known by his Latinized name Hedylogus. His name, from ἡδύς (hēdys, 'sweet') and λόγος (logos, 'speech') means somebody who speaks gently, softly mesmerizing people with his words. Apart from ἡδῠ́λόγος there are several other Greek words which describe this unique ability: μελιστάλακτος (melistálaktos) and μελισταγής (melistagḗs), which can be translated as mellifluous.
