6. The Cathedral of St. Trophime is opposite the museum. The Romanesque façade, dating from 1221, is a beautiful piece of architecture, enriched with statues and a bold arch supported by columns. The cloisters are intensely interesting, having been built in different periods--north and east sides Romanesque of the twelfth and thirteenth centuries, west about 1380, and south about 1505. 7. The Avenue des Alyscamps is the Roman cemetery of the city, just without the ramparts, put up during the reign of the Emperor Constantine. On either side of the avenue there are altogether 153 stone sarcophagi, the 33 large ones having retained their lids. The Alyscamps, when consecrated as a Christian burial-place, became so famous that bodies were brought great distances in order that they might enjoy the privileges supposed to be the lot of those who were buried there. 8. Church of St. Antoine, an interesting Gothic building. 9. Church of St. Honorat, partially eleventh century. THE ROAD TO AIX-EN-PROVENCE leaves Arles from the Avenue Victor Hugo, and after winding a little for about twelve kilometres, with trees interfering with the view, goes due east in a straight line across the open plain called La Crau (pronounced ‘Crow’). It is a strange level waste of round stones, very uniform in size, which the torrents of innumerable ages have brought down from the Alps. The early peoples of Provence were mightily impressed with these monstrous pebbles, and Strabo has preserved the legend that Zeus rained them down on the earth to scatter the Ligurian tribesmen who often attacked the adventurous Phœnician traders and colonizers. The heat of the sun on the mass of stones, which has a depth averaging from 30 to 45 feet, produces the phenomenon of the mirage, and the conditions of wind and temperature are always inclined to be different to less exposed places. A clear sunrise over the mountains north-east of the Crau is a memorable sight. The desert of stones, broken here and there with lines of cypresses, is full of a strange shadowiness under the crimson-streaked sky as the eastern light grows in intensity, and one half expects to see a caravan of camels and the burnous of Arabia in place of the country cart of the French peasant. The curiously isolated ridge called Les Alpines is prominent to the north wherever one goes between Nîmes and Salon. Salon is a cheerful town at the very edge of the Crau. The main street has a bright and almost Parisian touch, with its numerous cafés having their tables under the shade of old plane-trees. There is a fourteenth-century château, and in the Church of St. Laurent, a Gothic building of the same period, is the tomb of Michel de Notre Dame, Catherine de Medici’s favourite astrologer. Another church is dedicated to St. Michael, and is a century earlier.
