Ancient Roman Marble
View large Explore # 372
A tabletop of ancient roman marble on display at the Natural History Museum, London.
Marble is a metamorphic rock resulting from regional or rarely contact metamorphism of sedimentary carbonate rocks, either limestone or dolostone, or metamorphism of older marble. This metamorphic process causes a complete recrystallization of the original rock into an interlocking mosaic of calcite, aragonite and/or dolomite crystals. The temperatures and pressures necessary to form marble usually destroy any fossils and sedimentary textures present in the original rock.
This Roman table top is inlaid with large variety of ornamental marble excavated from tombs on Appian Way, a road constructed from Rome to Capua by Appius Claudius Caecus in 312 BC.
