[419] Now Joppa is not naturally a haven, for it ends in a rough shore, where all the rest of it is straight, but the two ends bend towards each other, where there are deep precipices, and great stones that jut out into the sea, and where the chains wherewith Andromeda was bound have left their footsteps, which attest to the antiquity of that fable. But the north wind opposes and beats upon the shore, and dashes mighty waves against the rocks which receive them, and renders the haven more dangerous than the country they had deserted. Now as those people of Joppa were floating about in this sea, in the morning there fell a violent wind upon them; it is called by those that sail there "the black north wind," and there dashed their ships one against another, and dashed some of them against the rocks, and carried many of them by force, while they strove against the opposite waves, into the main sea; for the shore was so rocky, and had so many of the enemy upon it, that they were afraid to come to land; nay, the waves rose so very high, that they drowned them; nor was there any place whither they could fly, nor any way to save themselves; while they were thrust out of the sea, by the violence of the wind, if they staid where they were, and out of the city by the violence of the Romans. And much lamentation there was when the ships were dashed against one another, and a terrible noise when they were broken to pieces; and some of the multitude that were in them were covered with waves, and so perished, and a great many were embarrassed with shipwrecks. But some of them thought that to die by their own swords was lighter than by the sea, and so they killed themselves before they were drowned; although the greatest part of them were carried by the waves, and dashed to pieces against the abrupt parts of the rocks, insomuch that the sea was bloody a long way, and the maritime parts were full of dead bodies; for the Romans came upon those that were carried to the shore, and destroyed them; and the number of the bodies that were thus thrown out of the sea was four thousand and two hundred. The Romans also took the city without opposition, and utterly demolished it.
