a surname of Diana in Italy, which she was believed to have received from the circumstance of Orestes having brought her image from Tauris in a bundle of sticks (fascis, Serv. ad Aen. 2.116; Solin. 1.2; Sil. Ital. 14.260). Fascelis, however, is probably a corruption, for the purpose of making it allude to the story of Orestes bringing her image from Tauris: the original form of the name was probably Facelis or Facelina (from fax), as the goddess was generally represented with a torch in her hand.
