Oecles

In the surviving mythic tradition Oecles appears as an Argive noble of the generation before the Trojan cycle and as the father of the famed seer Amphiaraus. Sources offer variant filiations: some attest him as son of Antiphates while others list Astacus as his father; the supplied materials do not reconcile these differences. He is consistently named as husband of Hypermnestra (also attested Hypermestra/Hypermestra), who is described in different accounts as daughter of either Thespius of Thespiae or Thestius of Pleuron. Within these genealogical matrices Oecles anchors Amphiaraus and related Argive families into wider heroic narratives and is counted among those who accompanied Heracles on the expedition against Troy.

The extant sources provided give no physical description or iconographic detail for Oecles. He is attested only in genealogical listings and narrative roll calls (for example as father of Amphiaraus and as a companion of Heracles), and no ancient descriptive passages specifying his stature, clothing, or distinguishing features are included in the cited materials. References to him appear primarily in prose summaries, genealogical indices, and scene captions naming Amphiaraus as "son of Oecles/Oikles."

The sources do not attribute supernatural powers, prophetic abilities, or divine status to Oecles; his notable functions are social and narrative. He is repeatedly identified as the father of the seer Amphiaraus and as the husband of Hypermnestra, and he is named among the companions who took part in Heracles' campaign against Troy. Any exceptional capacities in the tradition are assigned to his son Amphiaraus (seercraft), not to Oecles himself.
