If the man mentioned in both inscriptions was the same as Gildas' Vortiporius, we would expect the Latin and Irish forms to have been spelled *Vorteporigis and *Vortecorigas, respectively; the difference in spelling has led some to suggest that they are not the same person, though it is possible that they were related.
Se o home mencionado en ambas as inscricións fose o Vortiporius de Xildas, sería de esperar que as formas irlandesa e latina coincidisen; a diferenza na ortografía levou a algúns a suxerir que non son a mesma persoa, aínda que é posíbel que estivesen relacionados.
