Let us imagine we are in a village of an Aryan tribe in the Eastern Panjab something more than thirty centuries ago. It is made up of a few large huts, round which cluster smaller ones, all of them rudely built, mostly of bamboo; in the other larger ones dwell the heads of families, while the smaller ones shelter their kinsfolk and followers, for this is a patriarchal world, and the housefather gives the law to his household.
