[3] á Serkjum ‘on the Saracens’: The ethnic name Serkir and the region of Serkland ‘land of the Saracens’ are often vaguely defined in Old Norse literature, but generally refer to the eastern Mediterranean, including parts of North Africa, the Levant and the region south of the Caspian Sea; see Jesch (2001a, 104-7); Shepard (1982-5).
