The chalice and the altar-vessels, which date from the very cradle of Christian worship, since without these sacred vases the fundamental services of the religion of Jesus Christ could not have been performed, perhaps owe it to this exceptional fact that they are not spoken of before the eleventh century (Fig. 21). In truth, nowhere do we find an indication of their ordinary shape, nor of the mode of their manufacture in early times; but it is reasonable to suppose that the chalice originally was identical, as it was in times approaching nearer to our own, with the goblet of the ancients; or perhaps, to define it more particularly, was the well-known _hanap_ (drinking-cup), the earliest type of which tradition endeavours to trace to so early a date. At a later period, and until the time when the artists of the Renaissance period were called upon to remodel sacred ornaments, and they transformed them into marvels of art on which were lavished all the resources of casting, chasing, and glyptic, we observe that chalices continued to be manufactured with the greatest care, adorned with exquisite elegance, and enriched with all the brilliancy that art can give them.

Fifteenth Century (copied from the original belonging to N. Achille Jubinal).] All that can be said regarding the chalice applies equally to the monstrances and the pyxes employed to contain and to exhibit the consecrated wafers, as also to the censers, which originated in the Jewish form of worship, and which, in accordance with the successive epochs of Christianity, affected different mystical and symbolic shapes (Fig. 22). Of these M. Didron gives the following description:--“They were first formed of two open-work spheroids, in cast and chased copper, ornamented with figures of animals and inscriptions.” Originally they were suspended by three chains, which, according to tradition, signified “the union of the body, the soul, and the divinity in Christ.” At another period the censers represented, in miniature, churches and chapels with pointed arches. Again, at the Renaissance, they took the form of that now in use.
