Senua, also called Senuna.

AKA The Lost Goddess.

Senuna was a Celtic goddess worshipped in Roman Britain, whose name was at first read incorrectly as Senua. She was unknown until a cache of 26 votive offerings to her were discovered in 2002 in an undisclosed field at Ashwell End in Hertfordshire by metal detectorist Alan Meek. Her imagery shows evidence of syncretism between a pre-Roman goddess with the Roman Minerva (for a parallel, cf. Sulis Minerva, the Romano-British goddess worshipped at Bath).
