Histories

As for giving sworn pledges to those who are to receive them, this is the Scythian way: they take blood from the parties to the agreement by making a little cut in the body with an awl or a knife, and pour it mixed with wine into a big earthenware bowl, into which they then dip a scimitar and arrows and an axe and a javelin; and when this is done those swearing the agreement, and the most honorable of their followers, drink the blood after solemn curses.
