Sculpture: Spare Parts #13 by Paul Martia

Rings, squares and cogs crowd together like a city seen from above at night.

Spare Parts #13 is a contemporary sculpture by Paul Martia, made of steel, brass and copper. Welded assemblage, built from fragments of metal, became a vital language in modern sculpture from the mid 20th century, turning industrial leftovers into new compositions. Here a tall steel rod rises from a flat rectangular base, carrying two vertical clusters of welded rings, tubes, boxes and discs. The pieces are densely packed and gleam brass and gold against darker steel. It is 7.75 inches wide and 25 high.

Nothing spare about the effort involved.
