The Embarcation of St. Paula
Oil on canvas, 154 x 199 in. (390 x 505 cm.)
Dulwich Picture Gallery, London
The title notwithstanding, it is both St. Paula and her daughter St. Eustochium who are embarking for Palestine from Rome. As a widow, Paula is the woman with her head covered. Eustochium, head uncovered as a symbol of unmarried status, stands at her left.
The others pictured with Paula and Eustochium are presumably the former's other children. The Golden Legend says, "Only among all her children she had put her affection in Eustochium her daughter."
