The relief stelai used as tomb markers (sing. sema, pl. semata) in Grave Circle B at Mycenae are unique works of art dating from the transitional period between the Middle Helladic and the Mycenaean periods. This particular stele was placed above grave A. The stele consists of four fragments while the base consists of three. When it was accidentally discovered in November 1951, during the restoration works at the tomb of Clytemnestra, part of the stele was still affixed on the base. The stele is not well preserved, however, and it seems that the relief was not completed. On its upper half it bears a relief representation of a fight between people, lions and a bull. Two lions attack a dashing bull; in front of the bull a man lifts his spear and apparently strikes one of the lions; another man runs away from the scene. Under the men's feet are lines that perhaps were parts of the representation of a wall. Two engraved horizontal parallel lines appear on top of the figures, and to their right is an incised X. The triangle formed at the upper part of the X defines the distance between the lines at 0.04 m. The scene likely symbolizes the power and strength of a hunter-chief during the formation period of the Mycenaean aristocracy.
