Several legends are current as to the origin of this Musta temple, but they would hardly interest the average reader, though possessing a certain emphasis and fascination when related to one standing beneath the shadow of its lofty walls. When it was decided to erect the church, for some special reason it was particularly desirable to have the new edifice occupy the same site as the ancient structure already upon the ground. The question arose as to how this should be brought about. Knowing that the new temple must be years in course of construction, it was thought best not to destroy the smaller existing church until a new place of worship was completed. To meet this exigency, the one now bearing the grand dome was built outside and over the old one, the latter remaining undisturbed during the process. The dome, it is said, was thus constructed without raising any staging around it. When the walls and all of the new temple were finished, the old church was demolished and the débris promptly removed. This was certainly a remarkable architectural achievement. There are a dozen domes within the city walls, of less size, in view from the same point which takes in the Musta Pantheon, as it is often called. Many of the edifices to which they belong are costly structures, but they are not elegant or attractive. There are a few fine paintings in these city churches. One by Guido Reni in the church of Santa Maria, representing Santa Ursula, is highly prized, and is often visited by connoisseurs in art. It is doubtless an original. Unless one has a considerable amount of leisure time to dispose of, after a thorough inspection of the grand church of St. John, there remains little in the same line worthy of attention in Valletta. A careful study of this structure and the cathedral of Città Vecchia will doubtless satisfy the average traveler. There are said to be two hundred churches and chapels in the group, but this is, we should think, an exaggeration. Nevertheless, it is certainly true that a few less churches and a great many more schools would redound to the well-being of the inhabitants. CHAPTER XII.
