Oium or Aujum was a name for an area in Scythia, where the Goths, under King Filimer, arguably settled after leaving Gothiscandza, according to the Getica by Jordanes, written around 551. Jordanes does not give an etymology, but many scholars interpret this word as a dative plural to the widespread Germanic words *aujō- or *auwō- and means "well-watered meadow" or "island".
According to some historians, Jordans's account of the Goths' history in Oium was constructed from his reading of earlier classical accounts and from oral tradition. According to other historians, Jordans's narrative has little relation to Cassiodorus's, no relation to oral traditions and little relation to actual history.
Archaeologically, the Chernyakhov culture, which is also called the Sântana de Mureș culture, contained parts of Ukraine, Moldova and Romania corresponds with Gothic Scythia.
Jordanes states that King Filimer led the Goths in a search for suitable lands; when they arrived in Oium, they were delighted with the richness of the land. They crossed a bridge to get there, but when half the army had made it across, the bridge fell into ruin and so no one else could pass into the area anymore. According to Jordanes, the Goths claimed the land for themselves and defeated the previous inhabitants, the Spali.
The Goths left Oium in a second migration to Moesia, Dacia and Thrace, but they eventually returned, settling north of the Black Sea. Upon their return, they were divided under two ruling dynasties. The Visigoths were ruled by the Balþi and the Ostrogoths by the Amali. The account fits the patterns of the Wielbark culture and the Chernyakhov culture and the Santana de Mureş culture, which show a Germanic migration from the Vistula Basin to Ukraine.
