What the Greeks had to say about the kingdoms of India, its economy, society and people:
The whole population of India is divided into seven castes, of which the first is formed by the collective body of the Philosophers, which in point of number is inferior to the other classes, but in point of dignity preeminent over all.
The second caste consists of the Husbandmen, who appear to be far more numerous than the others. Being, moreover, exempted from fighting and other public services, they devote the whole of their time to tillage; nor would an enemy coming upon a husbandman at work on his land do him any harm, for men of this class, being regarded as public benefactors, are protected from all injury.
The third caste consists of the Neatherds and Shepherds and in general of all herdsmen who neither settle in towns nor in villages, but lead a wandering life and live in tents. By hunting and trapping they clear the country of noxious birds and wild beasts. As they apply themselves eagerly and assiduously to this pursuit, they free India from the pests with which it abounds,--all sorts of wild beasts, and birds which devour the seeds sown by the husbandmen. In return for clearing the land of wild beasts and fowls which devour the seeds sown in the fields, they receive an allowance of grain from the king.
The fourth caste consists of the Artizans. Of these some are armourers, while others make the implements which husbandmen and others find useful in their different callings. This class is not only exempted from paying taxes, but even receives maintenance from the royal exchequer.
The fifth caste is the Military. It is well organized and equipped for war, holds the second place in point of numbers, and gives itself up to idleness and amusement in the times of peace. The entire force--men-at-arms, war-horses, war-elephants, and all--are maintained at the king's expense.
