Spatial series

Single Column

Single Column

Single Column continued the concerns of the Two Column series, though focusing on a single illusionary spatial structure which is formed off the central block. All the other parts of the sculpture are concerned with supporting this column, either physically, or through illusionary spatial planes.

With all the previous sculpture in this group Cogswell had used units of two and three. In this he introduced units of five as well as the single unit. During the design process he realized he had unconsciously been using progressions of two and half degrees as well as ordered numerical progressions in the sizing of the units. These mathematical relationships were the result of only aesthetic considerations and not consciously planned.

These pieces from the early nineteen-seventies were explorations into the ability of specific forms to suggest illusionary surfaces that continue from the sculpture to the surrounding space. They mostly consisted of three units focused on a single central point or of two units with three divisions and with surfaces divided into rectangular graphic forms.

For these individual sculptures Cogswell worked in either local woods, fibreglass and resin, 1/4-inch plate aluminum or 1/4 inch corrosion resistant weathering steel. This Cor-ten type steel is very long lasting as the oxide (rust) which forms on the surface protects the steel from further corrosion and is self-healing in terms of surface damage.
