In late 1865 Julia Margaret Cameron began using a larger camera, which held a 15 x 12-inch glass negative. Early the next year she wrote to Henry Cole with great enthusiasm – but little modesty – about the new turn she had taken in her work.

Cameron initiated a series of large-scale, close-up heads. These fulfilled her photographic vision, a rejection of ‘mere conventional topographic photography – map-making and skeleton rendering of feature and form’ in favour of a less precise but more emotionally penetrating form of portraiture. Cameron also continued to make narrative and allegorical tableaux, which were larger and bolder than her previous efforts.

The title here refers to Lord Byron’s poem Maid of Athens, ere we part (1810). The soft, moody lighting conjures the poem’s theme of romantic longing. The embroidered cap is probably meant to suggest Greek folk costume. The last line of each stanza of the poem is ‘Zoë mou sas agapo’, which Byron translated as ‘My life, I love you’.

Cameron's friend and mentor, the painter G.F. Watts, wrote to Cameron, ‘Please do not send me valuable mounted copies … send me any … defective unmounted impressions, I shall be able to judge just as well & shall be just as much charmed with success & shall not feel that I am taking money from you.’ This photograph is one of approximately 67 in the V&A's collection that was recently discovered to have belonged to him. Many are unique, which suggests that Cameron was not fully satisfied with them. Some may seem ‘defective’ but others are enhanced by their flaws. All of them contribute to our understanding of Cameron’s working process and the photographs that did meet her standards.
