• 11 February 2005 - This "www.larips.com" web site released and announced as a resource to accompany the Oxford article, with clarifications and news. The initial pages in this release were the sections from the article's manuscript that Oxford University Press had chosen to eliminate from their edited version. I was therefore free to recycle these parts onto my own web site.

  Those first-release sections were:
  [The discovery story (crediting influences)]
  [Epigrams at the top of the article's manuscript]
  [Cube-puzzle layout (a concise model of the keyboard-tuning problems to be solved)].
  I also started three new resources in that release:

The church is "Maria de Victoria" from the 1730s. [Specification and essay by Kuhn]
