Carstian Luyckx, also known as the Monogrammist KL (1623 – c. 1675), was a Flemish painter and draughtsman who specialized in still lifes in various subgenres including flower still lifes, fruit still lifes, fish still lifes, pronkstillevens (sumptuous still lifes), vanitas still lifes, hunting pieces and garland paintings. He also painted animals and a few genre scenes. After starting his career in Antwerp he is believed to have worked later in France. Life Carstian Luyckx was born in Antwerp in 1623 as the son of David Luycx en Margriet Cloot. He was baptized on 17 August 1623. He studied painting under Philips de Marlier, a still life specialist, in 1642 and under Frans Francken III, a history painter, in 1645. In 1645 he became a master of the Antwerp Guild of St. Luke. He is documented in Antwerp up to August 1653. It is believed that he left Antwerp and worked in France as many of his later works carry French inscriptions. During his residence in France, Luyckx influenced other vanitas painters, including Simon Renard de St. André. It is not clear when and where Luyckx died but his death date is assumed to fall between the years 1657 and 1677. Work General Luyckx was a successful artist who worked in many still life genres and also painted animals and a few genre scenes. He fell into oblivion after his death. Only two dated works are known to exist, making it difficult to establish a chronology for his oeuvre. Luyckx is known to have collaborated with other Antwerp painters. The Gemäldegalerie Alte Meister in Dresden holds a painting referred to as Kitchen still life with vase of flowers, dead birds, fish and a cat. It is a collaboration of Luyckx with David Teniers the Younger who painted the architectural elements and Nicolaes van Verendael who painted the flowers in a vase. Luyckx painted the game still life, bird cage, dead fish and the cat. Pronkstillevens A large portion of his output consists of pronkstillevens, the sumptuous still lifes that were popular in Flanders and the Dutch Republic from the 1640s. Luyckx’ work in this genre was influenced by the artist Jan Davidsz. de Heem who was active in both Antwerp and the Dutch Republic. A representative example in this genre is the Opulent still life at the Montreal Museum of Fine Arts. This work dates from about 1650 and is
