Eusorus does not possess a narrative origin story in the surviving texts; instead he appears as a genealogical anchor in multiple classical sources. Apollonius Rhodius' Argonautica names Aenete as "daughter of goodly Eusorus," making him the progenitor of Cyzicus by that line (Argonautica 1.910 and surrounding genealogy). The Orphic Argonautica likewise calls Aenete the daughter of Eusorus. Hyginus (Fabulae) and other mythographic listings refer to Cyzicus as "son of Eusorus" in at least one tradition, while Apollodorus' genealogical compilations list an Acamas identified as son of Eusorus. These attestations show Eusorus functioning across variant local and poetic traditions as a named father or ancestor rather than as an actor with his own mythic biography.
No physical description, iconography, or cult imagery for Eusorus is preserved in the cited materials. All references to him appear in formulaic genealogical phrases (for example, "Aenete the daughter of goodly Eusorus bare..."), and none of the sources supply anthropological detail, portraits, or epithets that would describe his appearance or attributes.
The sources attribute no actions, supernatural powers, duties, cult, or narratives to Eusorus. He is used strictly as a genealogical and locative name within epic and mythographic lists. No myths record deeds, interactions, or agency for Eusorus himself; his function is to supply noble descent and localize descendant figures such as Cyzicus, Aenete, and Acamas.

Aenete
Aenete (Ancient Greek Αἰνήτη) is a mythological human figure recorded in Greek epic genealogies as the mother of Cyzicus, king of the Doliones. She appears in brief genealogical notices in the Argonautic tradition and is otherwise unattested as an active character, cult figure, or supernatural agent in the surviving citations.

Acamas
Acamas (Ancient Greek: Ἀκάμας) is a personal name recurrent in ancient Greek narrative traditions applied to multiple human characters (warriors, princes, suitors), once to a Cyclops, and once as a hound's name. Rather than a single supernatural entity, bearers of the name appear episodically across the Trojan War, Theseid, and Theban cycles as mortal actors whose deeds intersect with gods and fate.
