such as Carlo Saraceni (who returned to Venice in 1620), Bartolomeo Manfredi, and Simon Vouet. Gentileschi and Vouet would go on to have a professional relationship and would influence each other's styles. Vouet would go on to complete a portrait of Artemisia. Gentileschi also interacted with the Bentveughels group of Flemish and Dutch painters living in Rome. The Bolognese School (particularly during the 1621 to 1623 period of Gregory XV) also began to grow in popularity, and her Susanna and the Elders (1622) often is associated with the style introduced by Guercino. Although it is sometimes difficult to date her paintings, it is possible to assign certain works by Gentileschi to these years, such as the Portrait of a Gonfaloniere, today in Bologna (a rare example of her capacity as portrait painter) and the Judith and her Maidservant today in the Detroit Institute of Arts. The Detroit painting is notable for her mastery of chiaroscuro and tenebrism (the effects of extreme lights and darks), techniques for which Gerrit van Honthorst and many others in Rome were famous. Three Years in Venice (1626/7–1630) The absence of sufficient documentation makes it difficult to follow Gentileschi's movements in the late 1620s. However, it is certain that between 1626 and 1627, she moved to Venice, perhaps in search of richer commissions. Many verses and letters were composed in appreciation of her and her works in Venice. Knowledge of her commissions during the time is vague, but her The Sleeping Venus, today in the Virginia Museum of Fine Arts, Richmond, and her Esther before Ahasuerus now in the Metropolitan Museum of Art in New York, are testaments to her assimilation of the lessons of Venetian colourism. Naples and the English period (1630–1656) In 1630, Artemisia moved to Naples, a city rich with workshops and art lovers, in search of new and more lucrative job opportunities. The eighteenth-century biographer Bernardo de' Dominici speculated that Artemisia was already known in Naples before her arrival. She may have been invited to Naples by the Duke of Alcalá, Fernando Enriquez Afan de Ribera, who had three of her paintings: a Penitent Magdalene, Christ Blessing the Children, and David with a Harp. Many other artists, including Caravaggio, Annibale Carracci, and Simon Vouet, had stayed in Naples at some time in their lives. At that time, Jusepe de Ribera, Massimo Stanzione, and Domenichino were working there, and later, Giovanni Lanfranco and
