Elk-like animal of nordic countries (Scandinavia or Gangavia), known to the Romans only from hearsay. In the descriptions (Plin. HN 8,39; Solin. 20,3) zoological mirabilia of other animals (elk, elephant, rhinoceros) are mixed with possibly genuine memories of the giant deer, which died out in historical times. The Pliny report survives in the Song of the Nibelungs (16,937), where the achlis is replaced by the ‘Schelch’.
