Haynes from the Department of Greek and Roman Antiquities, British Museum, dated 27 April 1957 stating that 'the Research Laboratory have looked at your marble head and confirm our opinion that it is an ancient work. It probably comes from a decorative archaistic herm of the early first century A.D.'. He goes on to mention the four herms with heads of a very similar style in the Sale degli Horti de Mecente, Museuo del Palazzo dei Conservatori, Rome. Compare also an archaistic head of a kore with similar features in M.A. Tomei, Museo Palatino, Rome 1997, no. 99.
