The regretted Gollon has made me discover CV long time ago, so I owe his
soul a lot of respect. Unfortunately, I discovered his source, Murray,
years later and I hate to say that Gollon made a lot of mistakes, and me
too on my first book (Guide des échecs exotiques et insolites) because I
followed Gollon. Apologies to my French readers.
1) These 2 variants are nowhere called 'Kamil'.
2) Setup 2 is done by al-Masudi who said that it was invented by al-Khalil
ibn Ahmad (718-71). The Camels are at the sides of the board but their move
was not recorded. So our rule here is a pure speculation.
3) Setup 1 is found in Firdawsi's Shâhnâma. Gollon made a mistake: the
Camels are between Faras (Knights) and Fils (Elephants), check Murray,
p341.
The move that Murray gives p341 is cleary a speculation too as pointed out
by Sanvito and Panaino. Firdawsi's text is given on Murray p214. There we
learn that the Shutur (Persian for Camel) 'ran through 3 squares',
which, yes, means that they moved 2 square (ancient were counting the
starting square in), probably jumping (same thing is said of the
Elephant), but nowhere it is said that it was horizontally or vertically.
I agree that this speculation is believable, but it is good to know that
it remains a speculation.
If you have more elements in contradiction, please post them.
