A glass has certain dispositions, for example the disposition to shatter when struck. But what is this disposition? It seems on the one hand to be a perfectly real property, a genuine respect of similarity common to glasses, china cups, and anything else fragile.
The first saddle is believed to have been invented in 365 AD by the Sarmations. Proud horsemen who used their horses in battle and also sacrificed them to the gods, their saddle creations were brought back to Europe by the Huns.
It is supposed that the horse was first used by a tribe of Indo-European origin that lived in the steppes north of the chain of mountains adjacent to the Black and Caspian seas. Influenced by climate, food, and humans, the horse rapidly acquired its present form.
