Greater variety is seen in the shape of the central orphrey, which, being the more elaborate and expensive, is almost invariably found represented in the monuments of bishops, abbots, and other dignitaries, and in the effigies of priests of the richer churches. It sometimes, though rarely, consisted of a simple 'pillar' on the front and on the back of the vestment; usually this ornamentation was extended by the addition of branches of orphrey work given off on either side, which passed over the shoulder and joined the corresponding branches of the other pillar, the result being that the orphrey on front and back had the appearance of the Greek Ψ, or of a Latin cross with oblique arms. When the bands were so disposed, the pillar on the front was called the _pectoral_, the pillar on the back the _dorsal_, and the auxiliary bands, which passed over the shoulders, the _humeral_ orphreys. Very frequently this design was varied by omitting the part of the pectoral and dorsal bands above their intersection with the humeral; this resulted in the 'Y cross,' which we find in so many effigies in our cathedrals and churches. In a few examples the Y or Ψ is inverted, and in some it gives off auxiliary branches, so as to resemble (_e.g._) the figure ✶. It would, however, be waste of time and space to enter further into a discussion of what was not regulated by any definite rule, but depended on caprice, or, at most, on pecuniary considerations. More often than not the central orphrey, of whatever form, is combined with the edge orphrey, and is usually of a different pattern from it. In many early chasubles the front and back are charged with an embroidered Latin cross. This is also the case with the back of the modern Roman or slit vestment. When the Y orphrey was placed on the chasuble, the space between it and the neck on the back was usually filled with an elaborate floral design embroidered in gold or crimson. Sometimes (not always) this extended round the neck, and was repeated in front. To this ornament the special name of 'flower' has been attached.
