Magnes the shepherd

Classical sources (via Nicander as reported by Pliny) tell that a man named Magnes, a shepherd pasturing his herds on Mount Ida, discovered magnetic ore when the nails of his shoes and the ferrule of his staff adhered to a rock; the ore was said to be called 'Magnes' from that man. Later medieval compilers repeat or adapt the anecdote, sometimes relocating the shepherd to India or alternatively attributing the word's origin to places named Magnesia (Magnesia ad Sipylum, Thracian Magnesia, Magnesia ad Maeandrum). The account functions as an etiological explanation for the name of magnetite and related terms rather than as a historical biography.

Sources do not present a detailed physical description. Recurrent elements identify him by social role: a shepherd or shepherd boy tending flocks. Narrative details focus on his gear — a staff with a metal ferrule and shoes with nails — rather than personal features such as face, age beyond 'boy' in some variants, or clothing.

No supernatural powers are attributed. The 'ability' associated with Magnes is observational: he noticed the adhesive property of lodestone when metal parts of his footwear and staff stuck to a rock while pasturing his flocks. His role is explanatory — linking a human observer to the discovery and naming of magnetic ore — and sources do not ascribe ongoing influence, haunting, or demands.
