Freemasonry's "Mosaic" Pavement:

  "In  Masonic  tradition  Ceasar  Augustus  is  named  as the
  partron  of the masons in ancient Rome and is said  to  have
  been  Grand  Master of the Roman College of Architects. This
  society was organized into guilds with symbols based on  the
  tools  of  their  trade  such as the plumb line, the square,
  compasses, and the level. The College had initiation rituals
  involving  the  pagan  myth  of  death and rebirth which are
  familiar from the Egyptian Mysteries.  A  temple  built  and
  used  by the College was unearthed at Pompeii which had been
  destroyed by the volcanic eruption of Mount Vesuvius  in  71
  CE.  Among  the  symbols  discovered  in the temple were the
  double triangle of Soloman,  the  black  and  white  tracing
  board  (first  used by Dionysian Artificers), the skull, the
  plumbe line, the pilgrime's staff and the ragged robe. These
  symbols   later   emerged   in   medieval   and  speculative
  Freemasonry."  -- Howard, Michael, "The  Occult Conspiracy",

  " The floor of the tabernacle and the pavement of  Soloman's
  temple were thus ornamented.  Mosaic or tesselated pavements
  were common among the  ancients;  the Egyptians,  the Greeks
  and  especially  the  Romans  most ingeniously decorated the 
  floors and walls of their temples in this manner."
