Cercopes

Accounts vary. In some genealogies the Cercopes are placed among ancient generations (one tradition names them children of Oceanus and Theia), while other sources treat them as human-like brothers whose knavery invites divine or heroic punishment. Variant endings exist in different authors: one tradition records Zeus transforming them into monkeys (an etiological explanation linked to the name 'tailed ones'), while another report (attributed to Pherecydes in summaries) says they were turned to stone. Multiple name-pairs (e.g., Passalus and Acmon; Basalas and Achemon; Olus and Eurybatus; Candolus and Atlantus; Sillus and Triballus) across sources reflect local or transmission variants rather than a single canonical pedigree.

Physical descriptions in surviving sources are sparse and variable. The Greek name derives from κέρκος (kérkos, 'tail'), and some traditions and later mythographers present them with simian or tailed features; this etymology underlies accounts that identify or transform them into monkeys. In vase-paintings depicting the Heracles episode they appear bound with 'their faces pointing downwards' — a scene-specific depiction preserved in visual art rather than a general anatomical portrait. Overall, imagery ranges from rascally human-like brothers to tailed, simian-associated figures depending on context.

Sources attest to mischievousness, skill at theft, lying, and general comic subversion of order; they are proverbial tricksters who 'roamed the world' and harried mortals and heroes. Their best-attested narrative action is stealing Heracles' weapons while he served Omphale and being captured and humiliated by him. Beyond agility, deceit, and provocation, the provided material does not ascribe a consistent set of supernatural powers; some accounts record divine metamorphosis as a fate (transformation into monkeys or into stone) as narrative resolutions rather than catalogued abilities.
