Baudhāyana's Dharmasūtra, dated to the centuries immediately preceding the start of the common era, states five customs that distinguish the South of the subcontinent from the North (conventionally divided by the Vindhya mountain range).
The Northern customs are distinguished as being - trade in wool, consumption of rum (alcohol made from sugarcane), trade in animals having two rows of teeth (horses etc), making a living as a warrior, and travelling by sea. Not sure what to make of the 'travelling by sea'.
