Harpagus, the general of Cyrus, was ravaging Asia Minor, and he invested Phocœa. As the Ionians in the town found that they could hold out no longer, their general, Dionysos, thus addressed them:

“Our affairs are in a critical state, and we have to decide at once whether we are to remain free, or to bow our necks in servitude, and be treated as runaway slaves. Now, if you be willing to undergo some hardships, you will be able to secure your freedom.”

Then he advised that they should lade their vessels with all their movable goods, put on them their wives and children, and leave their native land.

Soon after this Harpagus saw a long line of vessels, their sails swelled with the wind, and the water glancing from their oars, issue from the port and pass away over the blue sea towards the western sun. All the inhabitants had abandoned the town. Dionysos had heard a good report of the Ligurian coast, and thither he steered, and was welcomed by his countrymen who had settled there half a century before.

But the Ligurians did not relish this great migration, and they resolved on massacring the new arrivals, and of taking advantage of the celebration of the Floral Games for carrying out their plan. Accordingly they sent in their weapons through the gates of Marseilles, heaped over with flowers and boughs, and a party of Ligurians presented themselves unarmed, as flocking in to witness the festival. But other Ligurian girls beside Gyptis had fallen in love with and had contracted marriages with the Greeks, and one of these betrayed the plot. Accordingly the Phocœans closed their gates, and drawing the weapons from under the wreaths of flowers, slaughtered the Ligurians with their own arms.

From Marseilles the Greeks spread along the coast and founded numerous other towns, and, penetrating inland, made of Arles a Greek city.

In the civil war that broke out between Cæsar and Pompey, Marseilles, unhappily for her, threw in her lot with the latter. Cæsar, at the head of his legions, appeared before the gates, and found them closed against him. It was essential for Cæsar to obtain possession of the town and port, and he invested it. Beyond the walls was a sacred wood in which mysterious rites were performed, and which was held in the highest veneration by the Massiliots. Cæsar ordered that it should be hewn down; but his soldiers shrank from profaning it. Then snatching up an axe, he exclaimed, “Fear not, I take the crime upon myself!” and smote at an oak. Emboldened by his words and action, the soldiers now felled the trees, and out of them Cæsar fashioned twelve galleys and various machines for the siege.

Obliged to hurry into Spain, he left some of his best troops under his lieutenants C. Trebonius and D. Brutus to continue operations against Marseilles; the former was in command of the land forces, and Brutus was admiral of the improvised fleet. The people of Marseilles were now reinforced by Domitius, one of Pompey’s most trusted generals, and they managed to scrape together a fleet of seventeen galleys.

This fleet received orders to attack that of Brutus, and it shot out of the harbour. Brutus awaited it, drawn up in crescent form. His ships were cumbrous, and not manned by such dextrous navigators as the Greeks. But he had furnished himself with grappling irons, and when the Greek vessels came on, he flung out his harpoons, caught them, and brought the enemy to the side of his vessels, so that the fight became one of hand to hand as on platforms, and the advantage of the nautical skill of the Massiliots was neutralised. They lost nine galleys, and the remnant with difficulty escaped back into port.

The besieged, though defeated, were not disheartened. They sent to friendly cities for aid, they seized on merchant vessels and converted them into men of war, and Pompey, who knew the importance of Marseilles, sent Nasidius with sixteen triremes to the aid of the invested town.
