"From the Greek writers we get some idea of Persian education; but it applies only to the nobility, and there was no place for what we should call intellectual pursuits. From what we can gather, the sons of Persians of note were weaned from the ‘harem at the age of five (when for the first time they were allowed in the presence of the father) and until they were twenty or more they were brought up at the royal court (or in the provinces at the satraps’ court) Emphasis was laid on speaking the truth and learning the examples that the legends provided; older children might listen to the judgements of the royal justices. Herodotus says that among the Persians the thing most prized after valour in battle was to be the father of many children, we can understand that he aim was to contribute the maximum to Persian military strength, and the result must have been a population explosion at the higher social level."
