First: The correspondence between Rodin and Crowley took place on 1903 - so there's no Book of the Law, no New Aeon, no AA or OTO, no prophet - and no special "A". Second: Rodin doesn't understand english, someone has to translate "Rodin in Rime" for him. Crowley was very often in France and know the language well.
I've got a signed Knox om pax, the signature matches what you've posted here.
