XV.i.39), Megasthenes is said to have noted that it was a regular custom in India for the "philosopher" caste (presumably Brahmins) to submit "anything useful which they have committed to writing" to kings,[4] but this detail does not appear in parallel extracts of Megasthenes found in Arrian and Diodorus Siculus.[5][6] The implication of writing per se is also not totally clear in the original Greek as the term "συντάξῃ" (source of the English word "syntax") can be read as a generic "composition" or "arrangement", rather than a written composition in particular. Nearchus, a contemporary of Megasthenes, noted, a few decades prior, the use of cotton fabric for writing in Northern India.
