Dusking is a project by the artist Lucy Wright—a newly invented tradition, conceived as the counterpart to the morris dancing that takes place on 1 May marking the arrival of summer. Taking place instead on 31 October, it invites participants—who join in remotely around the world—to ‘dance the sun down’ and honour the gifts of rest, reflection and replenishment associated with the darker months of the year. 'Mirie it is' is Lucy’s own contribution to this continuing tradition, a 3-part performance embodying each of the three stages of scientific twilight—civil, when the sun dips between 0 and 6 degrees below the horizon; nautical (when it’s below 12 degrees – and most stars can be seen with the naked eye) and astronomical, when just a little light is still left in the sky.
