This paper is prompted by a careful study of the ancient evidence and of the waters and coasts of the Salamis Channel, which has led me to a new conception of the battle. I proceed from the assumption that the ancient evidence is sound and that, if it is interpreted with respect, it provides a fairly close framework for the course of the battle. To this framework some additions can be made by means of local knowledge, whether gained at first or at second hand. The paper is divided into five sections: the topography of the Salamis Channel, the evidence for the battle, the manoeuvres of the day and the night before the battle, the day of battle, and an Epilogue with an Appendix on the new Scholia to the Persae.
