Description

The Witch of Agnesi is a sculpture created in 1959 by F E McWilliam and installed in 1960. This abstract piece is made of cast bronze and is mounted on a concrete base. It stands approximately 2.5 meters high and 1 meter wide at its widest point. The sculpture consists of a stack of four panels that alternate between concave and convex lateral curves, with each panel increasing in size from the base. The surface of the panels is deeply roughcast, featuring a circular eye-like detail on the convex side of the top panel and four small rings on the lowest panel. The panels are connected by short pegs, and the lowest panel rests on a circular plate.

The sculpture is positioned above a pool of water, next to which is a plaque inscribed with the following: ‘THE WITCH OF AGNESI / SCULPTURE BY FE MCWILLIAM. 1959 / COMMISSIONED BY THE LONDON COUNTY COUNCIL. RESTORED AND RE-ERECTED TO MARK / THE OFFICIAL OPENING OF PHASES IA AND II OF THE AVERY HILL STUDENT VILLAGE / SPONSORED BY BANKERS TRUST COMPANY. VARSITY FUNDING. GRIMLEY. MOUNT ANVIL. STEPHENSON HARWOOD COOPERS AND LYBRAND. UNIVERSITY OF GREENWICH / [university symbol] / THE UNIVERSITY OF GREENWICH’.
