[Ir., black, dark].
Legendary Irish druidess, also known as Duibhlinn, who gave her name to Dublin. When Dub learned that her husband, Énna (2), had taken a second wife, Áide or Aeté, she caused the drowning of her rival together with her family. In revenge, Margenn, a servant of Áide, cast a sling at Dub, killing her; she fell into a large pool at the mouth of the Liffey, which came to be known as Dubh-linn, ‘Dub's pool’, or Dublin. Although the pool once assured the passage of ships to the port of Dublin, modern dredging has eliminated it.
