Erecura (also found as Herecura, Aerecura, Eracura) was a goddess worshipped in ancient times, often thought to be Celtic in origin, mostly represented with the attributes of Proserpina and associated with the Roman underworld god Dis Pater. She appears with the latter in a statue found at Oberseebach, Switzerland and in several magical texts from Austria, once in the company of Cerberus, another, probably, with Ogmios. A further inscription to her has been found near Stuttgart, Germany. She may originally have been an earth goddess, associated with such attributes of fertility as the cornucopia and apple baskets; she may also have been associated with Silvanus and the Rhine Valley.. Green describes Aericura as a 'Gaulish Hecuba.'
Representations of Erecura are most commonly found in the Danubian area of Southern Germany and Slovenia, but they also occur in Italy, Great Britain, and France. Her inscriptions are concentrated in Stuttgart and along the Rhine.
The theonym is of unclear origin. It has been connected with Latin aes, aeris 'copper, bronze, money, wealth', era 'mistress' and the name of the Greek goddess Hera. Many different Romanised forms of this goddess’s name occur: Aeraecura at Perugia; Aerecura at Mainz, Xanten, Aquileia and Roşia Montană; Aericura at Sulzbach, Malsch, Eracura in Mautern, Austria, Ercura at Fliehburg, Erecura at Cannstatt, Tongeren and Belley in Aube; Heracura at Stockstadt am Rhein, Herecura at Cannstatt, Freinsheim and Rottenburg am Neckar, where the form Herequra is also found.
Epigraphic inscriptions in the Roman Empire tended to use capital letters. Nonetheless, less literate members of the Roman Empire’s community sometimes misinterpreted the phonemic value of a given letter of the Latin alphabet, as apparent in the inscriptions to Belatucadrus. In the Classical Latin alphabet, the capital letters A and H are not dissimilar in appearance and so may easily have been confused by less literate sections of the populace: hence, perhaps, the initial alternation between H ~ A in forms of the name. A name of the form */aireˈkura/ or */hereˈkura/ appears to underlie the alternations Aeraecura ~ Aerecura ~ Aericura ~ Eracura ~ Ercura ~ Erecura ~ Heracura ~ Herecura ~ Herequra.
Though the goddess herself may be Celtic, it is open to question whether the name is of Celtic origin or even Indo-European. The Proto-Celtic lexicon contained a root *kur - ‘circle’, developing into Old Irish curu and a root *kurr- ‘corner,’ surviving as Welsh cwr ‘edge’. The element *kur-, occurring in the name of this goddess and of the supposed male counterpart, Arecurius, may also be a contraction of Proto-Celtic *kawaro- ‘giant, hero,’ and so cognate with Irish curadh, Early Irish cur, curad, caur, ‘hero, champion,’ Welsh cawr, Cornish caur, ‘giant,’ Gaulish Kaúaros (Polybius), Cavarillus, ‘a hero, mighty,’ (root kewa-, kû-, ‘be strong’); Sanskrit çavîra, ‘mighty,’ çura, ‘hero;’ Greek kúrios, ‘lord.’ At entry 101 of his Indogermanisches etymologisches Wörterbuch, Julius Pokorny reconstructs *āper- as a root denoting ‘shore, waterside’, surviving in Epirus, German Ufer ‘riverbank’, which would have rendered *āφer- and then āher- in Proto-Celtic. Whether the goddess-name Veracura, attested at Petronell-Carnuntum, is an alternate phonological form of Aerecura, is a different epithet for Aerecura, or is a name of a different goddess, is arguable.
