Lockport is among the most distinguished of Lyman Kipp’s post and lintel assemblages. Post and lintel refers to the ancient Greek architectural innovation in which a horizontal element rests above two supporting vertical elements. Inspired in part by the shadows of half-completed buildings on construction sites, Kipp first conceived his sculptures by manipulating small wood blocks. By the late 1970s he had begun to experiment with aluminum. Lockport’s aluminum surfaces are painted bright blue, reflecting the artist’s use of bright primary colors almost from the beginning of his career as well as his interest in the relationship between color and form. Kipp’s commitment to large-scale sculpture led him to co-found ConStruct, a Chicago gallery devoted to monumental sculpture and collaboratively owned by its exhibiting artists, who include Mark di Suvero and Kenneth Snelson, both represented in Storm King’s collection.
