“My work is to bring the peripheral into focus,” says sculptor Cyrus Tilton in his artist statement. Indeed, Tilton’s sculptures reside in the space between the conscious and the unconscious, an area rich with the potential for imaginative play. In “Mend,” two realistic renderings of elephant’s tusks stand upright as though they are walking, with just the sculptural suggestion of a torso coming into view above them. With this piece, and many of Tilton’s other works now on view at Vessel Gallery (471 25th St., Oakland) in the show Periphery, the surrealist coupling of imagery prompts the viewer to fill in the disjuncture with their own narrative. Tim Rice’s nearly meditative paintings are also included in the show, complementing Tilton’s works with their large-scale ethereal patterns. With his “Thread” series, Rice works in an intuitive process of palette-knifing curved shapes into thin oils to create a calligraphy-like scripture of abstract, organic penmanship. Together, the works bring clarity to the shapes and shadows that lurk in the corners of our visual and mental margins.
