The two paintings are an extraordinary example of portraiture and an exceptional document of the costume of the time. The accurate description of luxury objects expresses a refined taste and lover of luxury, underlined by the richness of the fabric of the dress of the lady. The letter resting on the table in the second portrait is addressed to "Monsieur le Comte [...] Verone", next to it is an edition of Virgil’s work. Book, paper, pen and the little sword are symbols of the social rank and cultural level of the character portrayed.
