In the early years of the twentieth century, the striking scientific develo
pments of the period included a great increase in popular and professional
attention to non-Euclidean geometry. One of the leading scholars of the sub
ject was Henri Poincare, who was also a widely read theorist of the scienti
fic discovery process, keenly concerned with the role of the intuition and
the subconscious. His writings, and those of this interpreters, could well
have increased the appeal of four-dimensional geometry for artists already
attracted to the possibilities presented by these concepts. The working not
es of one such artist, Marcel Duchamp, record directly his debt to ideas li
nked to Poincare--an example of the interaction of greatly different parts
of the wider culture.
