Note 26 — Chapter I · SAXON AND WELSH TRADITIONS.
Reading edition
Aurel. Vict. cap. 41. Lappenberg, referring to this fact (Thorpe, i. 47), asks, “May not the name Erocus be a corruption of Ertocus, a Latinization of the old-Saxon Heritogo, dux?” I think not; for an Alaman would have been called by a high and not low German name, Herizohho, not Heritogo. I think it much more likely that his name was Chrohho or Hrôca, a rook.
