The Greek accounts you seem to be referring to are usually describing people in Persia and Elam as “Ethiopian” or dark-skinned , not “Negrito” in the modern ethnographic sense. Herodotus is the main source often cited in these discussions, and later writers on the internet sometimes stretch that into claims about a “Negrito population,” but that wording is not standard historical terminology.

What the Greek sources actually suggest

  • Herodotus is often quoted as saying parts of the Persian army or population included “Ethiopians,” which in Greek usage generally meant dark-skinned peoples, not a specific modern race label.
  • Some modern writers connect this to Elamites and other populations in ancient Iran, arguing that Greeks saw them as dark or “burnt-skinned”.
  • The term Negrito itself is a much later label used for certain populations in Southeast Asia, especially in the Philippines, Malaysia, and the Andaman Islands, so it does not naturally fit ancient Persia.

Likely answer

If your question is, “What did Greek writers report about dark-skinned people in Persia?”, the answer is that they reportedly described some groups as Ethiopian-like or black/dark-skinned. If your question is specifically about “Negritos of Persia,” that appears to be a modern misunderstanding or an internet-based claim rather than a standard historical category.

Important caution

The source that makes the Persia claim is a modern commentary article, not a primary Greek text, and it presents an interpretive argument rather than settled scholarship. The more established academic discussion of “Negritos” places them in Southeast Asia , not Persia.

TL;DR: Greek writers were said to describe some ancient Iranian or Elamite peoples as dark-skinned or “Ethiopian,” but “Negrito population of Persia” is not a standard historical identification.
