In this article, the author considers the use of the title basileus in relation to the Macedonian monarchs before Alexander the Great. He shows that the evidence we have does not prove the point that the Argeads ruling prior to the reign of Philip II bore the formal title basileus. As to Philip, it is not ruled out that some epigraphic documents attest the employment of the title basileus under him. Nevertheless, none of them can be regarded as irrefutable proof in the relation, and therefore it has to be recognized that at the present the question of Philip’s use of the official title basileus remains open.
