thought by most scholars to be represented in this painting, Giovanni Arnolfini and Giovanna Cenami, were of equal status and rank in the courtly system, so the theory would not hold true. On the opposite side of the debate are scholars like Margaret Carroll. She suggests that the painting deploys the imagery of a contract between an already married couple giving the wife the authority to act on her husband's behalf in business dealings. Carroll identifies Arnolfini's raised right hand as a gesture of oath-taking known as "fidem levare", and his joining hands with his wife as a gesture of consent known as "fides manualis". Although many viewers assume the wife to be pregnant, this is not believed to be so. Art historians point to numerous paintings of female virgin saints similarly dressed, and believe that this look was fashionable for women's dresses at the time. Fashion would have been important to Arnolfini, especially since he was a cloth merchant. The more cloth a person wore, the more wealthy he or she was assumed to be. Another indication that the woman is not pregnant is that Giovanna Cenami (the identification of the woman according to most earlier scholars) died childless, as did Costanza Trenta (a possible identification according to recent archival evidence); whether a hypothetical unsuccessful pregnancy would have been left recorded in a portrait is questionable, although if it is indeed Costanza Trenta, as Koster proposed, and she died in childbirth, then the oblique reference to pregnancy gains strength. Moreover, the beauty ideal embodied in contemporary female portraits and clothing rest in the first place on the high valuation on the ability of women to bear children. Harbison maintains her gesture is merely an indication of the extreme desire of the couple shown for fertility and progeny. There is a carved figure as a finial on the bedpost, probably of Saint Margaret, patron saint of pregnancy and childbirth, who was invoked to assist women in labor and to cure infertility, or possibly representing Saint Martha, the patroness of housewives. From the bedpost hangs a brush, symbolic of domestic duties. Furthermore, the brush and the rock crystal prayer-beads (a popular engagement present from the future bridegroom) appearing together on either side of the mirror may also allude to the dual Christian injunctions ora et labora (pray and work). According to Jan Baptist Bedaux, the broom could also symbolize proverbial chastity;
