Running until January 2000, it is entitled "Cracking Codes: the Rosetta Stone and decipherment".

WEBSITES Stone - megaliths, menhirs, dolmens, and henges - looms large on the Internet. Stone Pages (www.stonepages.comdmeozzi HomEng.html) is one of the best of dozens of websites. The site is the work of an Italian couple who have documented and photographed 288 megalithic sites in Britain, Ireland, France and Italy. The quality of text (in good English, as well as Italian) and images is well above average. Their coverage of Stonehenge, for example, is evocative and informative. But if you need to know when the gift shop is open, go to English Heritage at www.english-heritage. org.uk If you can get past the rather whimsical introduction, Megalithia (www.anima.demon.co.ukstones) is a useful site for closer study of stone circles in the British Isles, with its directory of hundreds of little-known sites.
The Great Pyramid at Khufu remains the biggest man-made pile of stones on the planet. Get some sense of its grandeur, and lots of statisitcs, at www.pbs.orgwgbhnovapyramid.
Few lumps of stone have generated as much heat as the Elgin Marbles, 56 sculpted frieze panels stripped from the Acropolis in Athens by the Earl of Elgin in 1801. The case for the restitution of these treasures - still in the British Museum (www.british-museum.ac.uk) - is expressed with fierce elegance at the website of the Melina Mercouri Foundation (www.mercouri.org).
Sculptors, architects and engineers have long battled against the nature of the material to create things which earn the cliche, a 'miracle in stone'. Look at the contenders: Chartres Cathedral (superbly illustrated at www1.pitt. edumedart menufrancechartrescharmain. html); the Taj Mahal (www.savory.orgphil Agra.html0; Christopher Wren's version at St Paul's (stpauls.london.anglican.org ); Michelangelo's David (see it at the Galleria dell'Accademia site, www. sbas.firenze.itmuseiacca01.htm); But what is stone, anyway? Dozens of university geology department websites can give you the answers. For a really close-up look, try the University of North Carolina's Atlas of Igneous and Metamorphic Rocks, Minerals and Textures (www.geolab.unc.eduPetuniaIgMetAtlasmainmenu.html). This large collection of photo-micrographs reveals the dazzling crystalline structures of what, to the untutored eye, would seem very ordinary lumps of rock.
The same could be said for some of the stones prized by the exponents of Suiseki - the mineral world's answer to bonsai. Try the Suiseki site at www.felixrivera-suiseki.com to see how popular the Japanese art of finding stones which remind you of something - anything - has become in California and elsewhere.
Most of the 382 kilos of moon-rock grabbed by the Apollo missions still resides in the vaults of NASA's Johnson Space Center in Houston, Texas. You can get a fair idea of what there is to see - and as much information as you are ever likely to need about the rocks themselves - at the Center's Astromaterials Curation site (www-curator.jsc.nasa.gov).
Some will argue that the only way to appreciate stone is to work on it with hammer and chisel. Anyone so moved will find inspiration and hard practical advice at Learning Stone (www.learningstone.net), the website of the Portland Sculpture Trust.
Here, you can learn about the geology, natural and social history of Portland and its stone - the stuff used by Wren, Nash, Hawksmoor and others in the re-building of London. And then book yourself onto a stone-carving course in a Portland quarry (see above for details).
