The cylinder and stamp seals published here belong to a collection bequeathed to the late R. W. Hutchinson by Olga Petrovna, Baroness da Maydell. She had bought them from various dealers both in the Middle East and in Europe, probably all between the two World Wars. Mr. Hutchinson invited me to publish some of those that came from Mesopotamia during historic times, and planned to publish the prehistoric stamp seals himself. The collection includes also Achaemenid, Sassanian, Egyptian, Cretan and prehistoric stamp seals which have not yet been published. Following his deeply regretted death in April 1970 the collection was bequeathed to Liverpool University, where it is in the care of the School of Archaeology and Oriental Studies, except for nos. 19 and 33 which he had given to me earlier. The Liverpool registration is given in parenthesis after the publication number. The description “seals” does not exactly apply to nos. 26 and 33, which are “eye-beads” as described by Professor W. G. Lambert in the RA 63 (1969), 65–71. Measurements are given in millimetres, height × diameter of cylinders; the dimensions of stamp seals and eye-stones are stated in full. 1. (RWH 1.) Abstract pattern made with two sizes of drilled hole, in high relief. 17 × 18·5. Light grey baked (?) clay. Jemdet Nasr type. 2. (RWH 3.) Pattern of two doubly-enclosed eye-lozenges; the spaces above and below are rilled with short, deeply-cut lines; in high relief. 15 × 13. Pink felspar. Jemdet Nasr type.
