During the Middle Ages no attention was paid to this fact, and those stations which had been perfectly wholesome in the Classic Epoch were rendered pestilential, and dwindled from populous cities to a cluster of fever-smitten peasants' hovels. In later times this desperate condition of affairs called for remedy. Louis XIV. sent engineers to examine and report on the state of this region, and works were begun which have been maintained and extended annually, the raising of dykes against overflow by the Rhone and by the sea. Drains have been cut in all directions to carry off the stagnant water, opening by traps into the sea. The extent of dyke now reaches two hundred and thirty miles. The banks of the two main branches of the Rhone are protected, as well as the sea-face of the Camargue, the triangle between them, and the annual cost to the country to keep them in repair is one hundred and twenty thousand francs. A flood, however, often breaks through the banks, and submerges a large district. On such occasions the additional expense is heavy.

Now, what is the result of all this outlay? The engineers and scientific authorities of the coast-works and dykes are pretty unanimous in saying that a great mistake was made in the beginning by Louis XIV. The Rhone ought never to have been embanked. What should have been done was to keep open the mouths of the lagoons, to preserve them from festering.

Formerly, the large island of the Camargue, occupying nearly twenty thousand acres, was periodically inundated by the Rhone, and when the waters fell, a film of the richest deposit was left behind, just as in Egypt the Nile overflows and fertilises its delta. At every overflow eighteen thousand cubic yards of alluvium was deposited over this district, all of which is now carried into the Mediterranean and thrown down in the construction of new bars; utterly wasted.

In the time of the Roman domination the Camargue was a second Egypt, and was called "The granary of the Roman army;" and Arles was given the designation of "The Breasts," so flowing with plenty was it held to be. At the initial cost of millions of pounds, and an annual outlay of five thousand pounds, the Camargue has been reduced to absolute sterility.

The protected lands, deprived of the sweet water which would have washed from them the salt that now spoils their fertility, and of the natural dressing that Providence sends down to them every spring and autumn, are now productive of only a little coarse wiry grass and thistles, and the dried soil is white with saline efflorescence. At the present day the value of land in the neighbourhood of Arles that is subject to periodic inundation is three times that of the land guarded by costly embankments against the bounties of the river.

On descending the sinuous course of the lesser Rhone the hills disappear, the horizon is level as the sea, and all around is desert. Then the current of the Rhone seems to fail wholly, the waters of the river and of the lagoons on both sides of its bed mingle, and become confounded in one sheet. All nature is dead. The dull and sluggish water, streaked with lines of ooze, extend on all sides as far as the eye can reach. The effects of the mirage add bewilderment. One can hardly distinguish water from sky. Nothing can be more dreary than this naked surface, hushed into silence, where vegetation is reduced to a few tufts of rushes and tamarisks.

But, suddenly, out of the marshy, submerged plain, a strange pile of buildings is seen cutting the horizon, half a castle, half a cathedral, imposing in a mass as it towers above the fragile and squalid hovels crouched at the feet. This building is Les Saintes Maries.

Probably nowhere in the world is to be seen a spot so desolate and so wretched. The village is planted at the extreme west angle of the Camargue. It can be reached by one road only, rough to travel over, and impracticable in winter. This road leaves Arles, or rather Trinquetailles, opposite Arles, traverses the marsh of the Grand Mar, follows the dyke of the river, and then threads its way among morasses, and over soil white with salt, and burning under the rays of the sun. Once in the year this route is crowded with pilgrims, who come to pay their devotions at the spot where it is supposed that the Three Marys, Mary, the mother of James, Mary Salome, and their servant Sara, landed. The legend is somewhat mixed. According to one version, those who came to Provence, flying from the persecution raised by the Jews, were Lazarus, Mary Magdalene, and Martha. Lazarus, as we have seen, has been appropriated by Marseilles as its apostle; Martha has been settled at Tarascon, and Mary Magdalene has been given a cell in La Sainte Baume. Here, at Les Saintes Maries, however, the apostolic three are said to be Mary, mother of James, Mary, wife of Cleopas, and Sara, their servant; but a concession to the other tradition is made, in that it is allowed that these three brought with them Lazarus and Martha.

Nothing was known of all this till the time of good King René. The church at this point was called in the sixth century S. Maria de Ratis, S. Mary of the Boats, by S. Cæsarius, Bishop of Arles. William, Count of Provence, in his will, A.D. 992, gives it the same designation; so Raimbald, Archbishop of Arles in A.D. 1061, "The Church of the Ever Virgin Mother of God, Mary of the Boats." So also Bertrand II., Count of Provence, at the same date. Two bulls of popes in 1123 and 1200 speak of the church as that of S. Mary on the Sea. So does Gervais of Tilbury. In 1241 Raymond Berengarius, Count of Provence, entitles it Notre Dame de la Mer. And so it continued to be called in documents down to 1395. If not Our Lady of the Sea, it was S. Maria de la Mar, of the Mere, the Lagoon.
