Gabbros = a coarse-grained igneous stone, same minerals as basalt. Gabbro is also the name given by the Italian artists to a rock essentially composed of feldspar and diallage, called by the French geologists euphotide.
Gargoyle = an elevated carved grotesque face which is a rainwater spout, spitting or gushing water from its mouth during a rain storm.
Galdar, (Gran Canaria) = is the location of a Prehistoric painted cave with geometric spaces and paintings, unusual for a prehistoric cave.
Galatea = an important mythical name in stone lore. Pygmalion is the name of a sculptor who makes a marble statue of a girl so lovely that he falls in love with it. He asks Aphrodite to give it life and after his wish is granted, Pygmalion marries this former sculpture and names her Galatea.
Ganosis = wax or encaustic finish on marble. Such a finish tended to softly yellow the surface of the stone, but also protected it from erosion if it were out-of-doors.
Glacier = glaciers are huge sheets of ice, and when glaciers retreat, they carve out landforms in many shapes and sizes. They also transport and eventually drop off stones far from their place of origin. These peripatetic stones are called glacial erratics.
Glacial Erratics = these stones differ from the size and type of rock native to the area in which they eventually come to rest and consequently are one indicator that can mark the path of prehistoric glacier movement. The erratic takes their name from the Latin word errare, which means to wander, to roam, or to ramble. It also means to be mistaken, to be wrong, or to err. Although erratics can be any size, we usually use the term to refer to large boulders. Some erratics are angular, but the classic erratic is somewhat rounded off, the abrasive action of transport having carved off any softer outer layer to leave a particularly durable centre. In MILESTONE, four erratics were carved; Susanna Specht and Carlos Lizariturry each carved one, and Atsuo Okamoto carved two.
Glyptic = art of engraving ornaments. If the drawing is sunken it is known as diaglyphic, if it is in relief anaglyphic. The word anaglyph is also used in sterioptics, to refer to the impression of three dimensions.
Gravestone = "Early grave markers were actually stones and boulders that were placed on graves for a strange and superstitious purpose. It was believed they were needed to keep the dead from rising from their graves. The weight of the markers was meant to keep them from climbing out from beneath the heavy rocks."
Grub-saw = a hand-saw used for sawing marble slabs into strips, perhaps a word inherited from Irish masons. A grub-saw is a bit of ordinary steel tapered like a carpenter's saw, with no teeth, just a few notches along it and a supporting piece of wood along its back which also serves as a handle. As soon as the mason chases in the fillet line, he pours sand and water on it and then pushes the grub-saw back and forth.
Gudgeon = metal pin.
