Seven virtues
The "Catechism of the Catholic Church" defines virtue as "a habitual and firm disposition to do the good." Traditionally, the seven Christian virtues or heavenly virtues combine the four classical cardinal virtues of prudence, justice, temperance and courage (or fortitude) with the three theological virtues of faith, hope and charity. These were adopted by the Church Fathers as the seven virtues.
Fortitude (Botticelli)
Upon first glance, the eye is pulled to the most illuminated point of the painting: the face of Fortitude. Her gaze is turned down and away from the observer and because of this, her expression is perceived as passive and uninterested. This was a characteristic feature of Botticelli's female figures. It is a fascinating contrast to the theme of the title because if she represents strength, why does she express otherwise? This work, which is one of seven virtues, was intended to be placed high upon a wall. This would be higher than the eye level of the viewer, therefore requiring them to look upward. In the line-up of all seven paintings of the virtues, Fortitude is the first. Perhaps her gaze is intended to literally and figuratively watch over the other virtues as well as the viewers. Without strength, one can never fathom taking on the other six virtues.
