Here is a tidbit from Tony Anderson's (excellent!) Bread and Ashes which will be of interest to fans of Central Asian culture:

The way became very steep and we led the horses, thank God, while Rezo encouraged them with strange Ratchuelian cries of 'Achoo!' and 'Brrr!'....

This is of interest because, while the scene is in Ratcha, i.e. the Caucasus of northwest Georgia, anyone who has ridden a horse in Mongolia* will recognize these commands as the Mongol words for "Giddy-up!" and "Whoa!" Perhaps not amazingly surprising, given the central events of Mongol history, but interesting to see it far away and in liguistically very different country.

*Not too ridiculous a clause, given that this blog does in fact have a few such readers.
