Note 87 — Chapter V · THE ENTR’ACTE: B.C. 490–480.

In some histories of Greece, discredit is cast upon Herodotus’ assertion that the preparation for the great invasion was begun in the last years of Darius. In the absence of evidence, this denial of the stated fact must rest on the basis of general probability.

In reference to this point I would urge that the most noticeable feature of Darius’ policy towards the west is its extreme tenacity of purpose. His plans had met with the severest checks in the course of their operation, yet he and his brother Artaphernes had persisted in their designs of conquest and acquisition in Europe, whenever circumstances rendered military and political interference possible.
