her father's death, although there are no known works assignable with certainty to this period. It is known that Artemisia had left England by 1642, when the English Civil War was just starting. Nothing much is known about her subsequent movements. Historians know that in 1649 she was in Naples again, corresponding with Don Antonio Ruffo of Sicily, who became her mentor during this second Neapolitan period. The last known letter to her mentor is dated 1650 and makes clear that she still was fully active. In her last known years of activity she is attributed with works that are probably commissions and follow a traditional representation of the feminine in her works. It was once believed that Artemisia died in 1652 or 1653; however, modern evidence has shown that she was still accepting commissions in 1654, although she was increasingly dependent upon her assistant, Onofrio Palumbo. Some have speculated that she died in the devastating plague that swept Naples in 1656 and virtually wiped out an entire generation of Neapolitan artists. Some works in this period are the Susanna and the Elders (1622) today in Brno, the Virgin and Child with a Rosary today in El Escorial, the David and Bathsheba today in Columbus, Ohio, and the Bathsheba today in Leipzig. Her David with the Head of Goliath, rediscovered in London in 2020, has been attributed by art historian Gianni Papi to Artemisia's London period, in an article published in The Burlington Magazine. Artistic importance The research paper "Gentileschi, padre e figlia" (1916) by Roberto Longhi, an Italian critic, described Artemisia as "the only woman in Italy who ever knew about painting, coloring, drawing, and other fundamentals". Longhi also wrote of Judith Slaying Holofernes: "There are about fifty-seven works by Artemisia Gentileschi and 94% (forty-nine works) feature women as protagonists or equal to men". These include her works of Jael and Sisera, Judith and her Maidservant, and Esther. These characters intentionally lacked the stereotypical "feminine" traits—sensitivity, timidness, and weakness—and were courageous, rebellious, and powerful personalities (such subjects are now grouped under the name the Power of Women). A nineteenth-century critic commented on Artemisia's Magdalene stating, "no one would have imagined that it was the work of a woman. The brush work was bold and certain, and there was no sign of timidness". In Raymond Ward Bissell's view, she was well aware of how women and female artists were viewed
