Glass, 12.25 grams, 28.36 mm. Early 4th millennium BC. A D-shaped blue glass seal matrix shaped as a reclining bull, the head moulded in the round and the body and legs indicated by defined incisions. Behind the head, a deep circular perforation enters the shoulder and exits through the upper rim of the piece for the suspension cord. On the reverse, a geometric design is incised comprising a lozenge and triangle above a transverse bar, all executed as rectilinear incisions joining roundels; the design appears to be a stylized human being holding a linear object in his or her right hand.
