Note 101 — Chapter VI · THE MARCH OF THE PERSIAN ARMY. PREPARATIONS IN GREECE.
Reading edition
The expedition to Thessaly must have been in the spring of 480. The Thessalian deputies came to the Isthmus “as soon as they were informed that the Persian was about to cross over into Europe” (H. vii. 172). Xerxes spent the winter of 481–480 at Sardes, and started thence “at the beginning of the spring” (H. vii. 37).
