Compare the headshot of my Lizaar above, with that her tail female ancestress *Turfa, below, photographed on her way to the UK in 1937. As an aside, I think that *Turfa’s photo below was taken at her documented stopover in Port-Said in Egypt, not in Jeddah as the comment on the Arabian Horse Archives hypothesizes.
This is what a good Arabian horse head looks like in my books. Deep, really deep, round jowls; fine cup-drinking muzzle; gentle, soft, intelligent, low-set eye; long ears on a mare; a gently lightly concave sloping profile.
I like it like that; I don’t want it more pronounced in my horses.
Your ideas of what a good head should be – there for do, means that it is functional, and furthers the survival of the species.
