in the standard setup: but the 4th row is arranged with reflection symmetry, so that the pawns of bulls face each other. Note that there is only one camel, but three knights (one knight replaces the missing camel). A sea monster replaces the vizier. The manuscript does not offer guidance as to how the extra pieces move. Duncan Forbes suggested in 1860 that the lion should combine the moves of rook and giraffe; the bull should combine the moves of picket and giraffe; and the revealer should combine the moves of picket and rook. (He gave the picket the move of the modern bishop, thus making the revealer identical to the modern queen.) Jean-Louis Cazaux suggested in 2012 instead that the extra pieces were simple leapers: the lion a (3,0)-leaper, the bull a (3,2)-leaper, and the revealer a (3,3)-leaper. Both assume that the sea monster is identical to the vizier: a (1,0)-leaper.
