Like Palmer, Calvert was inspired by Blake's Virgil illustrations, and during those years produced a series of wood-cuts, mostly very small. He also made some engravings on copper, one of which is 'The Bride' [Tate Gallery A00157]. It is inscribed 'O God! Thy bride seeketh thee. A stray lamb is led to thy folds.' But it already displays a lush and pagan eroticism that was eventually to overwhelm Calvert's Christian faith. Particularly telling in this evocation of a landscape flowing with natural abundance are the huge bunches of grapes on the vine growing up the tree in the centre. One of them, on the right of the tree-trunk, is so ripe that it is oozing great drops of juice.
Calvert's eroticism found its most intense expression in his tiny, extraordinary, wood engraving 'The Chamber Idyll' [Tate Gallery A00161], while the theme of natural fertility also appears in another wood engraving, 'The Ploughman'.
