A visitor to Cameron’s home in Freshwater on the Isle of Wight, Hatty Campbell was pressed into service as a model for eight photographs titled The Echo, The Guardian Angel, and The Vestal (shown here), referring to the virgin priestesses in Greek mythology charged with keeping the temple’s eternal flame alight. Almost without exception, Cameron’s female portraits bear biblical, historical, or literary titles, no doubt in part to make them more marketable than mere portraits of the photog­rapher’s family, friends, or house servants, but also because she looked for characteristics in her sitters that shared qualities with such subjects.
