XXIII. (109) After these things the architect of the tabernacle next prepared a sacred dress for him who was to be appointed high priest, having in its embroidery a most exceedingly beautiful and admirable work; and the robe was two-fold; one part of which was called the under-robe, and the other the robe over the shoulders. (110) Now the under-robe was of a more simple form and character, for it was entirely of hyacinthine colours, except the lowest and exterior portions, and these were ornamented with golden pomegranates, and bells, and wreaths of flowers; (111) but the robe over the shoulders or mantle was a most beautiful and skilful work, and was made with most perfect skill of all the aforesaid kinds of material, of hyacinth colour, and purple, and fine linen, and scarlet, gold thread being entwined and embroidered in it. For the leaves were divided into fine hairs, and woven in with every thread, (112) and on the collar stones were fitted in, two being costly emeralds of exceeding value, on which the names of the patriarchs of the tribes were engraved, six on each, making twelve in all; and on the breast were twelve other precious stones, differing in colour like seals, in four rows of three stones each, and these were fitted in what was called the logeum (113) and the logeum was made square and double, as a sort of foundation, that it mighty bear on it, as an image, two virtues, manifestation and truth; and the whole was fastened to the mantle by fine golden chains, and fastened to it so that it might never get loose; (114) and a golden leaf was wrought like a crown, having four names engraved on it which may only be mentioned or heard by holy men having their ears and their tongues purified by wisdom, and by no one else at all in any place whatever. (115) And this holy prophet Moses calls the name, a name of four letters, making them perhaps symbols of the primary numbers, the unit, the number two, the number three, the number four: since all things are comprised in the number four, namely, a point, and a line, and a superficies, and a solid, and the measures of all things, and the most excellent symphonies of music, and the diatessaron in the sesquitertial proportion, and the chord in fifths, in the ratio of one and a half to one, and the diapason in the double ratio, and the double diapason in the fourfold ratio. Moreover, the number four has an innumerable list of other virtues likewise, the greater part of which we have discussed with accuracy in our dissertation on numbers. (116) And in it there was a mitre, in order that the leaf might not touch the head; and there was also a cidaris made, for the kings of the eastern countries are accustomed to use a cidaris, instead of a diadem.
