Cinchonidine (2004) is a monochromatic etching from Damien Hirst's celebrated Spot series, presenting a circular arrangement of uniformly sized dots rendered in a refined palette of blacks, greys, and off-whites. Named after the pharmaceutical compound cinchonidine, the work exemplifies Hirst's systematic exploration of repetition, order, and scientific nomenclature. Hand-signed and numbered by the artist, this edition of 145 on Hahnemühle paper represents one of the more collectible print works from his Spot corpus. The restrained monochrome palette distinguishes it from the more widely known multicolour Spot paintings, lending it a particular elegance suited to discerning collectors.
