Aeracura seems to have been a a goddess of the underworld and of prosperity, whose cult centered on southern Germany and the north-west of the Balkans. The Roman god Dis Pater sometimes accomapanies her, in inscriptions, a statue, and magic spells. She shares her fruitful attributes with the Mothers, and may be a patron of miners.
Ogmios is a vaguer deity than the Irish god Ogma. Most of what we know about him comes from the Roman writer Lucan, who called him Hercules and described him as a master of persuasion and rhetoric. One inscription seems to record a dedication to him in fulfillment of a vow, and two curse tablets invoke him.
I was seriously tempted to call this piece “Cernunnos: God of Bling”. This may seem a wildly inappropriate way to describe a god revered by neo-Pagans and possibly the divine ancestor of the Gauls, but when so many images of him feature one or more torcs, which are simply enormous gold necklaces, how can you resist?
Check out my piece on Cernunnos and Flidais on the Dun Brython blog.
There are many different ways to become god of the dead. You can win the job by chance (Hades/ Pluto), you can be cast into the underworld by other gods (Hel), marry into the job (Nergal), or you can be the first person to die.
Donn was one of the invaders known as the Milesians, after their father Mil. He was the warlike one, while his brother Armaigen was the poet/judge. They eventually did take Ireland, but not easily, and Donn never got to enjoy their victory.
Although most of us think of Pluto as the Roman equivalent of the Greek god Hades, it is one of the Greek god’s titles, usually given as Pluton, Wealthy. This referred both to the earth’s fertility and the mineral riches that could be mined from it.
Apollo seems to have made a habit of swallowing up other gods. He took over (or was given, according to later mythology) the oracle of Delphi, which had belonged to his grandmother, Phoebe. He seems to have taken over the healing role of a very early Greek god, Paean, and also an Italian god named Soranus.
We don’t know a lot about Soranus, but he was worshipped at Mt. Soracte in Etruria, an area sacred to underworld gods like Dis Pater. Like most of the Italian gods, he had a partner, Feronia, whose sanctuary stood next to his. Although his cult may have involved the otherworld and the dead, his name is probably connected to that of the Etruscan god Suri, a god of purification and prophecy.
