Yes indeed, the Indo-Europeans loved their horses.

But they are not the only ones.

The Mongolians love their horses too. And let’s not forget the American Plains Indians. As soon as horses became available to them, some of them (notably the Lakota) re-structured their entire society around them, and began doing amazing things that the Europeans had never dreamt of (at least, not for many generations), such as hanging by their legs off the side of the horse to shoot a moving target with a bow.

Basically, horses are cool and beautiful, and also extremely demanding and high-maintenance. People tend to like them, but bear in mind that you do have to make them the focus of your entire life if you are going to do anything at all with them.

The “Parthian shot.” The Parthians were a people related to the Scythians and other horse-riding groups of Central Asia. That conical hat, too, is found among the Scythians, a people who live in what is presumed to be the Indo-European homeland.
