From Marseilles to Genoa the course lies toward the northeast along the coast of France. Thence, in going toward Messina, it turns toward the southeast, and follows the coast of Italy. The route may be traced very easily on any map of modern Europe. The reason why Messina had been appointed as the great intermediate rendezvous of the fleet was two-fold. In the first place, it was a convenient port for this purpose, being a good harbor, and being favorably situated about midway of the voyage. Then, besides, Richard had a sister residing there. Her name was Joanna. She had married the king of the country. Her husband had died, it is true, and she was, at that time in some sense retired from public life. She was, indeed, in some distress, for the throne had been seized by a certain Tancred, who was her enemy, and, as she maintained, not the rightful successor of her husband. So Richard resolved, in stopping at Messina, to inquire into and redress his sister's wrongs; or, rather, he thought the occasion offered him a favorable opportunity to interfere in the affairs of Sicily, and to lord it over the government and people there in his usual arrogant and domineering manner. After waiting a short time at Genoa, Richard set sail again in one of his small vessels, and proceeded to the southward along the coast of Italy. He touched at several places on the coast, in order to visit celebrated cities or other places of interest. He sailed up the River Arno, which you will find, on the map, flowing into the Gulf of Genoa a little to the northward of Leghorn. There are two renowned cities on this river, which are very much visited by tourists and travelers of the present day, Florence and Pisa. Pisa is near the mouth of the river. Florence is much farther inland. Richard sailed up as far as Pisa. After visiting that city, he returned again to the mouth of the river, and then proceeded on his way down the coast until he came to the Tiber, and entered that river. He landed at Ostia, a small port near the mouth of it--the port, in fact, of Rome. One reason why he landed at Ostia was that the galley in which he was making the voyage required some repairs, and this was a convenient place for making them.
