Focus on Reclining Figure (Lincoln Center) and discuss the Casts.
Moore's ideas for the sculpture may have been inspired by a flint stone, and he probably worked on some early clay or plaster maquettes in 1962 to develop his ideas, although none have been identified from those that survive.  Two of the maquettes were increased in scale to create half-size plaster working models, each supported by an armature.  Moore worked on the surface of the working models with chisels and other tools.  The completed plaster models were painted a dark colour, and placed in a pond at his home and studio at Perry Green, Hertfordshire.  Moore selected one working model (LH 518) for the Lincoln Center commission, and the other became Two Piece Reclining Figure No.5 1963-4 (LH 517).
Moore later had two bronze casts made of the plaster working model, measuring 2.35 by 3.72 by 1.65 metres (7 ft 9 in × 12 ft 2 in × 5 ft 5 in).  Moore presented one bronze cast to the Tate Gallery in 1978, along with 35 other works.  It was included in the exhibition to celebrate Moore's 80th birthday at the Tate that year, on the grass outside the gallery.  It has been on long-term loan to Charing Cross Hospital since 1980, where it is displayed in a pool that was created for it.  Moore donated the plaster working model to the Art Gallery of Ontario in 1974.  A second bronze cast is in the collection of the MIT List Visual Arts Center, mounted on a granite base; it was donated by Vera Glaser List in memory of Samuel Glaser. A third version is located on Henry Moore’s estate in Hertfordshire, England.The working model was scaled up again to create a plaster version of the full-size sculpture.  This sculpture was so large that Moore needed a new temporary studio, a metal structure covered with transparent plastic sheeting, to house it while he worked on it.  He used the same structure for his largest outdoor works until it became dilapidated and was removed in the 1980s.After the full-scale plaster model was completed in August 1964, it was cut into pieces to be sent to the Hermann Noack foundry in Berlin, where the pieces were cast in bronze and welded together again to create the completed work.  It was shipped on MS Finnclipper in July 1965, and installed at the Lincoln Centre on 21 September 1965.The 6-short-ton (5.4 t) full-size bronze sculpture (LH 519) is 16 feet (4.9 m) high and 30 feet (9.1 m) feet long, making it Moore's largest work at that date: it was twice the size of his stone UNESCO Reclining Figure of 1958, although his later Large Reclining Figure of 1984 would be 9 metres (30 ft) long.The work was removed in 2007, to allow the North Plaza at the Lincoln Center to be reconfigured.  The sculpture was reinstalled in a smaller pool in 2009, which was named the Paul Milstein Pool in 2011.
