The classic image of the cardinal virtue of Strength shows a woman subduing a lion, such as the one shown above of Forteza by German Renaissance engraver Hans Sebald Beham.
In some cases, Strength or Fortitude is shown with wings. Here we see her looking angelic, with a dragon.
In this painting of Fortitudo by Giotto, in the Scrovegni Chapel in Padua, Strength appears like a warrior, Athena-like. She holds a stave in her hand, and the lion appears on her shield, showing that she has both mastered the lion and assumed its qualities of courage for herself.
