Of the immense number of subjects represented on these jewels we have already spoken in the introduction to the jewellery of the period. For pendants formed of single figures executed in the round, the whole of ancient or mediæval imagery--with its figures of Pan or of wood-nymphs, centaurs, tritons, or mermen; nereids, mermaids or sirens; hippocamps, unicorns, dragons, and other creatures, real as well as fabulous, of the earth, air, or sea--was revived, or else transformed to suit the fancy of the Renaissance jeweller. The formation of many of these was frequently suggested by a monster pearl, unsuitable for ordinary jewellery on account of its baroque or misshapen form, introduced in a wonderfully skilful manner into the body or breast of a figure, which was completed in enamelled goldwork. In such adaptations the German jewellers, who seem to have revelled in technical difficulties, displayed extraordinary ingenuity. Among groups of several figures employed as subjects for representation, generally within a frame of ornamental design, scenes from ancient mythology predominate, the Judgment of Paris being a very favourite theme. But Christian allegories are not excluded: besides the frequent representation of Charity with her two children or her symbol the pelican, we find Faith, Hope, and Fortitude; St. George and the Dragon or St. Michael are also frequently met with; while amongst scriptural subjects of the Old and New Testaments or the Apocrypha, the Annunciation is perhaps the most popular.
