It will be sufficient to give one example of this prostitution of art and craftsmanship. This helmet after Negroli (Fig. 43), and a similar example, signed by Negroli, at Madrid, show how the canons of the armourer's craft were ignored at this period. It is true that the casque still provides a metal covering for the head, and that the comb gives an additional protection to the skull, but when we examine the embossed figures at the side--and marvellously good the embossing is--we find lodgements for the sword or spear which would most certainly help to detach the helmet from its wearer. As to the comb, it may fairly be cited as an example of all that is artistically worst in the late Renaissance. Its technical merits only emphasize this. The warrior is laid on his back to suit the required shape of the helmet, and to give point to his position his hair is held by two figures whose attributes seem to suggest that intercrossing of birds, beasts, and fishes which delighted the decadent mind of the period. The figures are human to the waist and end in a dolphin's tail. Angels' wings spring from their shoulders and leopards' claws from the junction of tail and waist. Not content with this outrage to the dignity of art, the craftsman ends his warrior in an architectural base which has not even the slight merit of probability which the tail of the merman might offer. In short it is an example of technical skill at its highest, and artistic perception at its lowest point. The shield from the Vienna collection (Fig. 44) is another example, like King Sebastian's suit, of meaningless decoration. The strap work does not in any way follow the lines of the shield, and the female figures seem to be introduced only to show that the craftsman could portray the human form in steel as easily as he could the more conventional ornament.
