Woman carrying oranges on head. Black woman smiled and waved at me. Seilacher thought that she just liked my hat, a desert-style pith helmet. The Germans were delighted when I first put it on, calling it my "tropical helmet."

Buxmann, The Professional Furnishers. Nama Craft Store-a Newveld enterprise. As per my introduction to this art at the Frankfurt Airport, the shape of the wood controls the carving of wood sculptures in Namibia. The sculptures appear misshapen until you are familiarized with the style. And then one sees something akin to Picasso. Or perhaps a !Xam San rain creature.

At the very center of the middle ofWindhoek, at the epicenter of the nation itself, was (other than diamonds) the greatest natural national treasure: the Gibeon meteorite fall (figure 4.7). Recall the prominent poster in the Survey that warned against illegal removal of meteorites from Namibia; Namibians were still smarting from the loss of much of the huge Gibeon meteorite fall to international dealers.

The meteorites of downtown Windhoek were set on harmonically stepped granite pedestals, composing a striking statuary that appeared to sweep down from the sky. One of the meteorites in the display was sliced and polished to show the angular crystalline Widmanstatten structure. From the brass plaque:

The largest known meteorite shower to fall to earth covered an area

360 kilometers long and 100 kilometers wide around Brukkaros.

Most fragments fell just southeast of Gibeon. [Gibeon was founded by Hottentot settlers who, under their chief, Moses Witbooi (father

of Hendrik Witbooi), named the settlement after the scene in the Old Testament where Joshua calls upon the sun to stand still as he avenges himself on the Amorites.] The explorer, J. E. Alexander, recorded the occurrences of the meteorites in 1838, although they had long been known to the local Namas who hammered pieces into implements.

A total of 77 pieces have been found having almost identical chemical compositions; these are believed to have initially been part of one large body over fifteen tons in weight which fragmented long before its individual pieces entered the Earth's atmosphere. The largest fragment found weighs 650 kilograms.

The meteorites are classified as octahedrites, the most common type of iron meteorites, and consist entirely of taenite and kamacite, two different crystalline phases of iron-nickel alloy, the former containing much more nickel than the latter. These two phases form alternating parallel crystal bands that are arranged in a triangular pattern referred to as Widmanstatten Structure [figure 4.8], a characteristic of all octahedrites. Besides Iron, the meteorites contain an average of 8% Nickel, 0.5% Cobalt, 0.04% Phosphorus, small
