A small Christian monument of centralised plan built against the West Wall of Apollonia was excavated and slightly restored by the Libyan Department of Antiquities under the directorship of the late Professor Goodchild during the sixties. In 1967 the present writer, then architect to the Michigan Apollonia Expedition, was commissioned to make a set of drawings of the monument as a basis for its publication by Professor Goodchild to appear in the Michigan Report. Professor Goodchild's untimely death in 1968 nullified the project and eventually in its stead only a cursory notice of the monument appeared. The substantive treatment of the monument, utilising the prepared set of drawings, was reserved for the long laboured Corpus of Christian Antiquities of Cyrenaica. Unfortunately in turn this design was frustrated by the death of Professor Ward Perkins in 1986 so that the detailed drawings of the monument remained unpublished for 25 years. In 1991 old prints of the drawings were recovered and are published here with a commentary.

This small square monument with a dome on four pillars giving a rudimentary cross-in-square plan is of late sixth century date. It is clearly sepulchral, whether it be a simple tomb or a martyrion. Thus in spite of its provincial guise it is of interest and significance (together with the Church at Qasr el Lebia) in the long vexed question of the origins of the ecumenical Byzantine cross-in-square plan.
