On my first visit to Cyrene in summer 1972 I was so intrigued by the figurative relief standing on the south side of the so-called Valley Street, immediately to the east of the modern village of Shahat, that I decided to include it in my doctoral thesis. I visited the site in the distinguished company of the late Prof. D. E. Strong, who was then my research supervisor, and Mr. Philip Kenrick. We spent together some hours in front of this fascinating monument discussing a number of points concerning the architecture of the building to which it belonged, the identification of the figures, the iconography of the then hypothetical portraits, and the reading of the inscription. A full description and discussion of the monument were given by Professor Strong in a lecture delivered at the British Museum on the occasion of the opening of the Exhibition of Libyan Antiquities on 14th June, 1973, and later published in theSociety for Libyan Studies Report. I returned to Cyrene in summer 1973 in order to make a more thorough examination of the relief and to produce a number of detailed photographs of the heads. The contents of this article are the result of these observations and the stimulating discussions I had with Professor Strong on the subject.For a comprehensive description of the relief I refer the reader to Strong's contribution in theFourth Annual Report, but it is appropriate to recapitulate briefly. The relief in question constituted the figured frieze of the entablature of a monumental gateway resting on Corinthian columns. Beneath the frieze, which must have been more than 11m long, ran an inscription in two lines of standard monumental Greek letters. All the architectural elements, including the frieze, are carved on a very gritty and shelly limestone. The state of preservation is very poor: the figures on the right hand block are almost completely lost and elsewhere heads and limbs have fallen off, in some cases being cemented back. The best preserved are the central figures, but even here the sugary limestone has eroded to some extent (Fig.Ia).
