While in Italy, Vigée Le Brun was elected to the Academy in Parma (1789) and the Accademia di San Luca in Rome (1790). In Naples, she painted portraits of Maria Carolina of Austria (sister of Marie Antoinette) and her eldest four living children: Maria Teresa, Francesco, Luisa and Maria Cristina. She later recalled that Luisa "was extremely ugly, and pulled such faces that I was most reluctant to finish her portrait." Vigée Le Brun also painted allegorical portraits of the notorious Emma Hamilton as Ariadne (1790) and as a Bacchante (1792). Lady Hamilton was similarly the model for Vigée Le Brun's Sibyl (1792), which was inspired by the painted sibyls of Domenichino. The painting represents the Cumaean Sibyl, as indicated by the Greek inscription on the figure's scroll, which is taken from Virgil's fourth Eclogue. The Sibyl was Vigée Le Brun's favorite work. It is mentioned in her memoir more than any other work. She displayed it while in Venice (1792), Vienna (1792), Dresden (1794) and Saint Petersburg (1795); she also sent it to be shown at the Salon of 1798. It was perhaps her most successful painting, and had always garnered the most praise and attracted many viewers wherever it was displayed. Like her reception piece, Peace Bringing Back Abundance, Vigée Le Brun regarded her Sibyl as a history painting, the most elevated category in the Académie's hierarchy.
