Night and Day was published in 1846 as part of Isaac Frost’s Two Systems of Astronomy, a remarkable work produced within the small Muggletonian religious movement. The illustration presents a geocentric universe, placing the Earth at the centre of creation. Although this view had long been abandoned by mainstream science, Frost combined religious belief, meticulous craftsmanship and one of the most advanced colour-printing techniques of the nineteenth century to create a chart of extraordinary beauty. Today, it stands not as a scientific reference, but as a rare document of how people once imagined the structure of the cosmos.
