I made some significant changes to this page. I followed up on some of the things Jean-Louis Cazaux was saying in the comments and incorporated them into the historical notes section. I added some photos of the piece from different times and places. I greatly expanded the movement section by discussing how the Rook moves on different types of boards and how this bears on our understanding of orthogonal. I renamed the Alternate Images section to Piece Graphics, added some new images, and formatted it with flexbox instead of a table. I added the other books I cited to the References section, providing links to online copies at Archive.org and Amazon links for purchasing them. I also removed Hans as an author, because in comparing this page with a much older version he had written, I found I had no longer kept anything he had written.
