A further point of identity, though only a minute detail, can be traced in the regulation that the Eucharistic oblate from which the priest communicated was, in the ninth century, larger than the loaves used by the people. So the Passover cakes (Shimmurim) used by the master of the house, and particularly the middle cake, pieces of which were distributed, were made larger than the ordinary Matzoth. Picard (1723) curiously enough reverses this relation, and draws the ordinary Matzoth much larger and thicker than the Shimmurim. The ordinary Matzoth he represents as thick oval cakes, with a single coil of large holes, which start outwards from the centre. Picard speaks of Matzoth made in different shapes, but he gives no details. In the Middle Ages, and, indeed, as early as Chrysostom (fourth century), the Church cakes were marked with a cross, and bore various inscriptions. In the Coptic Church, for example, the legend was "Holy! holy! holy is the Lord of hosts." Now, in a Latin work, _Roma subterranea_, about 1650, a statement is made which seems to imply that the Passover cakes of the Jews were also marked with crosses. What can have led to this notion? The origin is simple enough. The ancient Romans, as Aringhus himself writes, and as Virgil, Horace, and Martial frequently mention, made their loaves with cross indentations, in order to facilitate dividing them into four parts: much as nowadays Scotch scones are baked four together, and the central dividing lines give the fourfold scone the appearance of bearing a cross mark. It may be that the Jews made their Passover cakes, which were thicker than ours and harder to break, in the same way. But, besides, the small holes and indentations that cover the surface of the modern Matzah might, if the Matzah be held in certain positions, possibly be mistaken for a cross. These indentations are, I should add, very ancient, being referred to in the Talmud, and, if I may venture a suggestion, also in the Bible, I Kings xiv. 3, and elsewhere, Nekudim being cakes punctuated with small interstices.
