These photos of mathematical art are
from my trip to Europe in June 1999.

In Ávila, Spain, there is a museum exhibiting historical
artifacts from Roman times to the present. One Roman mosaic
floor includes a design representing the Whitehead link.
Also in Ávila, the Monasterio de Santo Tomas,
founded by Ferdinand and Isabella,
includes many heraldic decorations, including a yoke and arrows
whose rope is usually tied in interesting knots.
At the new Isaac Newton Institute for mathematics in
Cambridge, England, there are three sculptures
(based on the Borromean rings) by John Robinson,
entitled "Genesis", (??) and "Creation".
The sculpture below was designed by
John Sullivan
with Nat Friedman, using a computer program written by
Carlo Séquin to design sculptures similar to
some by Brent Collins.
The physical object was produced by Séquin on his
Fused Deposition Modeling (FDM) machine, a Stratasys 1650.
The gray parts are support structures to hold the overhangs of the yellow model
while they solidify, and will be removed later.
