Salonika has no very ancient history. It did not exist till after the death of Alexander the Great, when Kassander, who became king of Macedon, founded it in 315 B.C., and gave to it the name of his wife, Thessalonike, who was half-sister of the famous Macedonian conqueror, just as he bestowed his own upon another town, from which the westernmost of the three prongs of the peninsula of Chalkidike still retains the name of Kassandra. When the Romans conquered and organized Macedonia, Thessalonika became the capital of that province, remaining, however, a free city with its own magistrates, the πολιτάρχαι, to whom St Paul and Silas were denounced on their memorable visit. It is a proof of the technical accuracy of the author of the Acts of the Apostles, that this precise word occurs as the name of the local magistracy in the inscription formerly on the Vardar gate, but now in the British Museum. The description in the Acts further shows that the present large Jewish colony of Salonika, which is mostly composed of Spanish Jews, descendants of the fugitives from the persecutions of the end of the fifteenth century, had already a counterpart in the first. We may infer that Salonika was a prosperous town, and its importance in the Roman period is shown by the fact that Cicero, who was not fond of discomfort, selected it in 58 B.C. as his place of exile, and that Piso found it worth plundering during his governorship. But the sojourn of the Roman orator left a less durable mark upon the history of Salonika than that of the Apostle. It was not merely that two of his comrades, Aristarchos and Secundus, were Thessalonian converts, but mediæval Greek writers lay special stress upon the piety of what was called _par excellence_ “the Orthodox City”—probably for its conservative attitude in the Iconoclast controversy. Salonika furnished many names to the list of martyrs, and one of them, St Demetrios, a Thessalonian doctor put to death in 306 by order of Galerius[426] became the patron of his native city, which he is believed to have saved again and again from its foes. The most binding Thessalonian oath was by his name[427]; his tomb, from which a holy oil perpetually exuded, the source of many miraculous cures, is in the beautiful building, now once more a church, which is called after him; it was on his day, October 26 (O.S.), that in 1912 Salonika capitulated to the Greek troops, and there were peasant soldiers at the battle of Sarantaporon who firmly believed that they had seen him fighting against the Turks for the restoration of his church and city to his own people[428], just as their ancestors had beheld him, sword in hand, defending its walls against the Slavs. The story of his miracles forms a voluminous literature, and on the walls of his church his grateful people represented all the warlike episodes in which he had saved them from their foes. Some of these mosaics have survived the conversion of the
