In Celtic mythology, (specifically known from Switzerland), Artio was a goddess of wildlife, specifically the bear, and was worshipped at Berne, which actually means "bear". She was often called Artio of Muri. She may have been married to Esus. A similar goddess was Andarta.
Her name is derived from the Celtic word artos, bear, which may also be the source for the modern name Arthur.
Arto Records was a short lived record label based in the United States of America, from 1920 to 1923.
Arto Records was owned by the Arto Company of Orange, New Jersey which in turn was owned by the Standard Music Roll Company, a business which made player piano rolls.
Arto Records also pressed masters for other record companies, including Nordskog Records.
