Ad Herculem

The BAtlDir (page 416) cites only and echoes TIR Emerita (page 24) in describing the modern location of ad Herculem as "Novo Sancti Petri (Chiclana de la Frontera)"; however, neither BAtlas map 26 nor the TIR map place the symbol for ad Herculem anywhere nearly as far south as modern Novo Sancti Petri. The TIR map, in an inset at a scale of 1:250,000, places the station in a now-submerged area just offshore from the modern Playa de Sancti Petri, roughly due east of the Castillio de Sancti Petri (widely accepted location for the Hercules sanctuary). BAtlas 26 D5 at a scale of 1:500,000 opts for a location further north, roughly coincident with the place where a modern chapel stands on a peninsula named "Sancti Petri", site of piers, anchorages, and restaurants, as well as the dwindling remnants of older residences and structures.
