Denis Mitchell moved to Cornwall in 1930. He played an important role in the artistic development of St Ives following the Second World War. He was a founder member of the Penwith Society and was an assistant to Barbara Hepworth from 1949-59, working on many of her sculptures. In 1959 he began to make abstract sculptures in bronze using a local sand-casting foundry. Simple shapes can be cast by this method and the casts were initially rough, enabling him to use his manual skills to perfect and purify the surfaces. 'Praze' is a fine example of his streamlined single sculptural forms. It is a variation on a theme that he had begun to develop some years earlier. The title, 'Praze' is a Cornish place name.
