The Alhambra Theorem
Ralph Abrahamโ
27 August 2015
Abstract
The early evolution of geometric thinking produced geometric algebra in
ancient Greece, rhetorical algebra in early Islam, and eventually a precursor of
modern algebra in the repeating patterns of medieval textiles and wall decorations. This medieval craft mathematics culminated in the Alhambra in Islamic Spain. Here we tell the story of this milestone in the history of mathematics.
