The sapling was sourced from an eroding part of the coast, symbolising the changing margins of society. The occasion was marked with ceremony and accompanied by appropriate Blakely verses. It was witnessed by around sixty onlookers, who were encouraged to help fill the hole by each spreading a handful of dirt.
In 1765 at the age of 8, William Blake saw his first vision while walking on Peckham Rye. ‘A tree filled with angels, bright angelic wings bespangling every bough like stars.’
In collaboration with the Blake Society and the Forestry Commission, an oak sapling was saved from the eroding margins of England and transplanted to Peckham Rye as an invitation to future generations of Peckham Angels.
