Crouching
                              Cat was carved from a block of rough
                              Polyphant stone  (also
                                                          known as
                                                          Cornish
                                                          Greenstone).  
                                          It is 6.75" high, 14.5" long
                                          and 4.5" wide, and weighs
                                          20.6lb/9.35kg.  Polyphant is basically
                                  greenish-grey
                                  in colour,
                                      but it
                                        also can be flecked
                                        with a variety of other
                                          unpredictable colours.  
                    
                    Polyphant stone is a type of Elvan, a name used in
                    Cornwall and Devon for native varieties of
                    quartz-porphyry.  Greenstone is another name
                    for this stone and it is often used for parts of
                    buildings such as doorways so they can be finely
                    carved.  Most of the Elvan quarries are now
                    disused.
                  
                      
                   
                  Around 400 prehistoric
                          stone axes, made from greenstone, have been
                          found all over Britain, which from
                          petrological analysis appear to come from west
                          Cornwall.  Although the quarry has not
                          been identified, it has been suggested that
                          the Gear, a rock now submerged half a mile
                          from the shore at Penzance, may be the site.
                        
                      The
                      name Polyphant means 'Frog Pool' in Cornish.
