WEST PALM BEACH, FL.- For the next several months the Norton Museums celebrated painting by Paul Gauguin, Christ in the Garden of Olives, 1889 (illustrated at right), will be featured in the exhibition Gauguin: Maker of Myth at the Tate Modern, London, and the National Gallery of Art, Washington, DC. In this work Gauguin portrayed himself in a tragic, iconic mode as Jesus Christ in the Garden of Gethsemane on the night of his betrayal by Judas Iscariot. In a poignant reference to his attempted artistic liaison with Vincent van Gogh, which had recently ended in a debacle, Gauguin has given himself bright orange-red hairlike that of his erstwhile colleague and friend. During much of our paintings absence from West Palm Beach the Museum will display, instead, an almost exactly contemporaneous self-portrait by Van Gogh, likewise painted in the immediate aftermath of the contentious and aborted sojourn with Gaugu
