Her-sema-tawy

The supplied materials do not record a separate mythic origin for Her-sema-tawy as an independent being. Instead, Her-sema-tawy is attested in modern summaries and catalogues as a named form or epithet of Horus; Mythlok glosses the epithet as "Horus who unites the Two Lands," linking the name to the ideological role of unification of Upper and Lower Egypt, while Wikidata classifies Her-sema-tawy explicitly as a form of Horus and Wikipedia explains that Horus appears in many different recorded forms that are treated as distinct by Egyptologists (Wikipedia; Wikidata; Mythlok).

No unique iconography for Her-sema-tawy is documented in the supplied sources. Because Her-sema-tawy is a form of Horus, the closest available descriptions are those of Horus: Horus is most often depicted as a falcon or as a man with a falcon head (Wikipedia). The sources do not provide specific visual attributes or distinguishing regalia unique to the Her-sema-tawy epithet.

The sources identify Her-sema-tawy as an aspect of Horus emphasizing the political function of uniting the Two Lands and legitimizing kingship. More generally, Horus is described as a major deity whose functions include kingship, protection, healing, the sun and the sky; the supplied materials indicate Her-sema-tawy participates in Horus' broader association with royal authority and state unity rather than introducing distinct supernatural powers of its own (Wikipedia; Mythlok; Wikidata).
