The portrait of Lady Venetia Digby as an allegory of Prudence is both a memory of fresh beauty and an authentic symbolic "monument" to the lady's virtues, probably executed immediately after her early death in 1633.

Three cupids wear a laurel wreath on the noblewoman's head, a tribute to her virtue. Dressed in a large "old-fashioned" red cloak but with a hairstyle and jewels that correspond to the fashion of her time, the gentlewoman is seated on a simple square block of stone, a symbol of moral solidity.

Lady Venetia caresses two white doves, a symbol of innocence and conjugal fidelity, while holding a snake in her right hand, the traditional attribute of the virtue of Prudence. On the left, three allegorical figures lie defeated on the ground: in the background, Fraud, with two faces, chained; further on, profane love, blindfolded, and another cupid in tears, with the torch extinguished and his legs ending in a snake's tail, an allusion to sin.
