It would often happen to one digging deep in the earth to come upon the capital of a lofty column which still stood on its base far below; and builders were wont to seek for their erections no other foundations than some mass of ancient masonry, or on arches such as are commonly seen in cellars, or on some old wall or substructure existing on the site. And upon the very wrecks of the ancient buildings, as they fall to ruin, the builders set out casually the foundations of new houses, as if these fragments were great masses of rock, firm and trustworthy. It is evident that many of the old streets lie more than thirty feet below the level of those now in existence. On January 28th M. de Montaigne had colic, which, however, did not interfere with his customary movements, and passed one rather large stone and some small ones. On the 30th he witnessed the most ancient religious ceremony that still subsists amongst men--to wit, the circumcision of the Jews--and gave most attentive and profitable attention thereto. He had already visited their synagogue one Saturday morning, and heard their prayers, when they sang in irregular wise certain portions of the Hebrew Bible suited to the occasion, after the manner of the Calvinist churches. They are cadences of similar sound, but the discord is excessive by reason of the mixing together of voices of all ages, for even the youngest children are of the party, and all understand Hebrew but indifferently. They are no more attentive to their prayers than we are, for they talk of other things during their service, and exhibit little reverence for their mysteries. At the entrance they wash their hands, and inside they count it a curse to remove their headgear, but they do reverence, as their worship ordains, by bowing and kneeling. On the shoulders or on the head they wear certain pieces of linen decked with fringe; but to describe these details would take too much time. After dinner their doctors give instruction by turns upon the passage of the Bible for the day, speaking in Italian, and next an assistant doctor selects one of the hearers, or sometimes two or three in succession, to hold argument with the one who has been teaching upon the subject of his discourse. It seemed to M. de Montaigne that the man we heard displayed great eloquence and mental power in arguing his case.
