Possibly due to being worshiped in a harbor city, he was sometimes called "the lord of the holy sea,"[5] while in a balbale song of Nanshe he is described as "the tax collector of the sea."[6] However, his most common epithet, attested as early as the reign of the Early Dynastic king Enannatum I, was Lugal-uru16, "the powerful master."[5] Gudea in a royal inscription credits Nindara with giving him strength.[5] Like Nanshe, he was also associated with birds, specifically the dar bird (darmušen), possibly a francolin.[3]
