Blake met Catherine Boucher in 1782 when he was recovering from a relationship that had culminated in a refusal of his marriage proposal. He recounted the story of his heartbreak for Catherine and her parents, after which he asked Catherine, "Do you pity me?" When she responded affirmatively, he declared, "Then I love you." Blake married Catherine – who was five years his junior – on 18 August 1782 in St Mary's Church, Battersea. Illiterate, Catherine signed her wedding contract with an X. The original wedding certificate may be viewed at the church, where a commemorative stained-glass window was installed between 1976 and 1982. Later, in addition to teaching Catherine to read and write, Blake trained her as an engraver. Throughout his life she proved an invaluable aid, helping to print his illuminated works and maintaining his spirits throughout numerous misfortunes.
