Monumental Stela

Square Forms saw the reintroduction of a more geometrical approach. She had used such forms in the 1930s, most notably with the Constructive carving Monumental Stela, 1936 (BH 82, destroyed, repr. Herbert Read, Barbara Hepworth: Carvings and Drawings, 1952, pl.43), in which shallow rectangular planes appeared to be similarly shifted in progressive dispositions. [image source]

It is notable that the sculptor specifically remarked upon the ambition of such lost pre-war works, telling Alan Bowness in 1970 that more recently she had the 'space and time and money for materials' to realise them on a large scale (Bowness 1971, p.7).

Square Forms with Circles

The use of this geometry on such a scale was also recalled when Hepworth reconceived Square Forms as Square Forms with Circles, 1963 (BH 326, private collection, repr. Bowness 1971, pl.74) at nearly eight times the size. This enlargement differs in some details (the vertical rectangle is off-set further to the left) and has the roughened surface typical of Hepworth's monumental bronzes but here also developed out of the process of manufacture. A circular depression was cut into the face of the uppermost square, and an incised circle appears on the reverse of this element - suggesting potential removal - and on the reverse of that at the top left.

Squares with Two Circles

These circles became conical piercings in Squares with Two Circles, 1963. [image source]

The artist also took up this simplicity in ensuing drawings, especially the linear Square and Circle, 1963 (private collection, repr. Alan Bowness, Barbara Hepworth: Drawings from a Sculptor's Landscape, 1966, pl.55). [still looking for an image]

Nicholson, White Relief (Triplets)

As well as Hepworth's sculptures from the 1930s, this modified geometry and the effect of shallow overlapping planes relates to the reliefs of Ben Nicholson, both from that period and as resumed in the late 1950s. Especially notable is Nicholson's October 2 1934 (white relief - triplets), 1934 (private collection on loan to High Museum of Art, Atlanta, Georgia, repr. in col., Ben Nicholson, exh. cat., Tate Gallery 1993, p.144, no.55), where the top square is set to the right and punctured by a circle. [image source - not certain this is the work referred to, but it meets some of the criteria]

His reliefs of the 1950s are more often constituted of quadrilateral and rhomboidal planes, such as those found in 1957, April (Lipari), 1957 (private collection, repr. in col. ibid., p.186, no.111). [still looking]

Significantly, these reliefs made a virtue of the dense texture and uneven absorbency of the materials to achieve a mottled surface which may be compared to that favoured by Hepworth on her bronzes.
