Dicken said it meant "naked." Putting "naked" together with "athletic," I figured the word he heard must have been "gynmasia," but no, Dicken insisted: "Olympia" was the ticket, if you had a ticket.
Dicken, my apologies for ever doubting you. Now I'm reading Anthony Majanlahti's The Families Who Made Rome, and I come across Olimpia Maidalchini Pamphilj (1592-1657), the grasping, ambitious country girl who made herself into the Majorette-Domo of the Pamphilij clan. Majanlahti calls her "a tough, rich, bossy woman with a reputation for avidity." Her brother-in-law occupied the papal chair as Innocent X; satirists branded her la dominante or la papessa; sometimes, more bluntly, la pimpaccia. They saw her as "the only gatekeeper to the pope's favour and a corrupt one at that." Effectively exiled by Innocent's successor, she spent her sunset years giving away an impressive amount of money, but still died with a jaw-dropping two million gold scudi in cash. But Majanlahti adds:
Donna Olimpias's memory remained, blurrily, as that of a famous harlot, sand 'Olimpia' became a popular prostitute's psuedonym for centuries, visible even in Manet's famous nineteenth-century portrait of a female nude.So apologies, Dicken,and a retrospective salute to the girls of Cadiz who were merely taking their place in the narrative of western culture. There's a copy of Manet's "Olympia" here (gymnasia), along with a background essay which, however, offer no hint of her sacerdotal provenance.
