Caroline Walker's "Nocturnes" is a suite of four colored lithographs from 2023 that captures the progressive dimming of light across different evening hours, from early dusk through midnight. Published by the renowned Enitharmon Editions in London, each print is signed and numbered from an edition of 35, presented as full sheet impressions on wove paper measuring approximately 53 by 43 centimeters. The work demonstrates Walker's characteristic interest in atmospheric effects and temporal progression through the medium of lithography, a technique that allows for rich chromatic layering and tonal subtlety.
