The castle, which covered a large part of the site, had walls composed of solid rock, the superfluous material being cut away both on the inside and outside. In some cases the rock, which is a soft limestone, and decays by exposure, has given way quicker on one side than another, with the result that large masses of “wall” have fallen either flat on the ground, or in solid blocks down the cliffs. In other instances towers have toppled against towers, like trees cut at the foot, producing a most confused and overturned appearance, as if the result of siege or earthquake. With respect to the architecture, says Mérimée, “The exceptional situation of the town of Les Baux has given rise to a style which scarcely furnishes any indications of the ancient epochs of its history; however, I have seen nothing which appeared to be older than the twelfth century. A church in fair condition seems to be of the epoch of transition. In the right aisle are seen a cornice and transverse arch enriched with dog-tooth and zig-zag ornaments. The rest of the church has been repaired in the fifteenth century, and several very elegant chapels have been added to it.” This church is illustrated by Révoil. On the south side of the town a bas-relief of three large figures and part of a Latin inscription, carved to a great scale on the face of the rock, have given rise to some extraordinary theories. The figures are called Les Trois Maries or Tremaié. Many observers regard them as Roman, and suppose that they represent Marius (the conqueror of this district, about 100 B.C.), his wife Julia, and a Syrian prophetess or sorceress called Martha, who accompanied the great leader and foretold his victories. But M. Lenthéric, in his interesting work on the _Villes Mortes de la Méditerranée_, already referred to, takes an entirely different view. He contends that these figures represent Lazarus and the two Marys; and considers the existence of the church dedicated to the “Saintes Maries” (which we shall reach by and bye), together with the above figures and inscription, and the traditions of the country, sufficient proof that the family of Lazarus and their companions were really the first missionaries of Christianity in Southern Gaul. There is another large inscription and two more figures on another rock, but they are too much decayed to be accurately interpreted. There seems to be no doubt that a town has existed here from the time of the Romans, although no Roman architecture can now be detected. In mediæval times it was the home of the famous family of Les Baux, whose history (written by Jules Canonge) comprises much of that of Provence from the tenth to the fifteenth century.
