HOLLY Vs. MACHADOXLEAO & RedKooks: 7 Paintings of Heaven "7 Paintings of Heaven and The Lost Artwork" is an art collection by MACHADOXLEAO inspired by the Christian allegory "The Pilgrim's Progress from This World, to That Which Is to Come" by John Bunyan in 1678. In this story, Christian (the Pilgrim) leaves the City of Destruction (this world) and begins a journey to the Celestial City (that which is to come) after having a revealing dream.
