They are compared for the part each plays in their own tradition rather than for any attribute in common.

The herm, a bearded head on a pillar, is the cult you actually meet: boundaries, luck, and theft. Athletic Hermaia marked boys. He leads souls and goats with the same staff. A marketplace god before he is a cute messenger.
Ogham and the strong-man of the Tuatha. Irish saga, not a recovered temple list. Treat him as a literary champion unless a site turns up.
Greek Pantheon
God of messengers, commerce, thieves, and travelers. Son of Zeus and the nymph Maia, known for his cunning and speed.
Hermes is the swift messenger of the gods, wearing winged sandals and carrying the caduceus. He is the patron of boundaries and travelers, and the only god (besides Hades and Persephone) who can freely travel to the Underworld.
Celtic Pantheon
Inventor of the Ogham alphabet and champion of the Tuatha Dé Danann. His eloquence binds listeners with chains of gold that flow from his tongue.
Ogma is the son of **Elatha**, a Fomorian king, and therefore half-brother to the Dagda, Lugh, and Bres. Despite his mixed heritage, he fought for the Tuatha Dé Danann as their champion. In the Second Battle of Mag Tuired, he slew **Indech**, king of the Fomorians, and retrieved the sword **Orna**, which could recount the deeds it had performed when drawn. Ogma is credited with inventing **Ogham**, the earliest Irish writing system, whose letters are named after trees. The Greek writer Lucian described **Ogmios**, the Gaulish equivalent, as an old man leading willing captives by gold chains attached to his tongue, a vivid image of persuasive speech.
Ogma embodies the paradox of eloquence: words that are stronger than force, speech that binds more surely than chains. He is both warrior and poet, champion and scholar, reflecting the Celtic reverence for the power of language and the status of the filí (poet-seer) in early Irish society.
Comparisons pair figures that play a similar role across traditions, or that the myths connect within one. A shared role does not, by itself, establish a shared origin.
