From earlier research, other names for the Ore Mountains have also appeared in a few older written records. However, the names Hircanus Saltus (Hercynian Forest) or Fergunna, which appeared in the 9th century, were only used in a general sense for the vast forests of the Central Uplands. Frequently the term Miriquidi is used to refer directly to the Ore Mountains, but it only surfaces twice in the 10th and early 11th centuries, and these sources do not permit a clear identification with the ancient forest that formerly covered the whole of the Ore Mountains and its foreland.
