Architecture, from a set of allegories of the arts and sciences with grotesque motifs on black grounds

Engraving, part of a series of allegories of the arts and sciences with grotesque motifs, executed on black grounds by Étienne Delaune before 1573. This print consists of an allegory of Architecture, represented by a female figure, standing with her head turned to the right, under a double-tent. She lifts a carpenter's square with her left hand, and holds a compass next to her hip with the right hand; both tools are common attributes of this art. At her feet are additional elements of architecture: a roof, column drums, and an entablature. On either side is a lit oil lamp, likely symbolizing vigilance, and two olive and laurel branches, likely used to connect Architecture with virtue. On the upper part of the composition are two snails and two monstruous creatures, with the body of a swan with breasts, and with the head of a dog. On the lower part of the frame is a mask crowned by acanthus leaves, flanked to the sides by two creatures with beard and wings, their lower bodies ending on scrolling leaves, each blowing a conch. The function of these motifs in the allegory of Architecture is unclear.
