[1] Vifilsey: Name of an island, whose location is unspecified in Hrólf. According to ch. 1 of the saga (Hrólf 1960, 1-2), Vifill (or Vífill, see below) was the name of a wise commoner (karl) who was a friend of King Hálfdan and lived on this island. He had two dogs named Hoppr and Hó. He hid Hróarr and Helgi on the island after Fróði had killed their father and, when Fróði himself came looking for them there, adopted the ruse of calling out the dogs’ names in order to alert the boys to present danger. The pers. n. Vifill or Vífill is common in legendary sagas. The initial vowel of Vifill may be either short, as here, in a Type A3-line with resolution, or long (Type B), as emended in Edd. Min. (þeir í Vífilsey).
