Ashlar (Achelor, or Ashler)
Ashlar (Achelor, or Ashler)
hewn or squared stone used in building, as distinguished from that which is unhewn, or rough as it comes from the quarry. It is called by different names at the present day, according to the way in which it is worked, and is used for the facings of walls. "Clene hewen" or finely worked ashlar is frequently specified in ancient contracts for building, in contradistinction to that which is roughly worked.
