The terms kunstkammer, “chamber of art,” and wunderkammer, “chamber of wonder,” basically refer to the same thing—the age-old cabinet of curiosities. It is a room, or rooms, filled with a very personal, often eccentric collection that includes precious art, outlandish decorative pieces, preserved exotic species, and grotesque rarities like shrunken heads and dessicated mermaids (a fish body sutured to a monkey’s torso). Usually created by aristocrats and the wealthy, and dating from the 16th to the 18th centuries, these rooms were precursors to the modern museum, but they reflected the fancies, desires, even compulsions of their owners. You could call them cabinets of the unconscious. To celebrate turning 20, Lismore Castle Arts presents “Kunstkammer.” Curated by the art historian Robert O’Byrne, it is both a re-creation and a reinvention of the classic cabinet, and mixes marvelous historical objects with works of art by leading Irish and international artists. What connects the objects is for you to figure out. —Laura Jacobs
