Knight's Tour Egyptian Art 1888
Several beautiful knight's tour symmetries were made and published in 1888-1889. Here are some that come from the book called Memoires or Travaux Originaux Presentes et Lus a L'Institut Egyptien Publies sous Len Auspices de S. A. Mohammed-Said.
I have modified the tours in red by converting them from single circuit knight tours to two or more circuits per tour to show their complete symmetry and beauty. My tour conversions are with blue moves of the knight.
The last tour above needs no conversion because it is already a beautiful example of a complete 180 degree rotation symmetric single circuit knight's tour.
