The lentoid gem to the left of this (No. 539), as seen by the spectator, is of greenish serpentine. It is convex on both sides and has likewise a horizontal perforation. It represents, in beautiful intaglio, two horses standing on their hind-legs opposite each other, their heads leaning over in opposite directions. The tail of the horse to the left of the spectator is represented by a mere band; that of the other is bushy; to the head of each horse is attached an ornament, which probably belongs to the trappings. Between the heads of the horses we see two human figures, of which that to the left of the spectator has a Phrygian cap on its head, and extends its hands towards the other figure, whose head seems to be uncovered, and which is holding a round object in its only hand which is visible. On the third lentoid gem (No. 541), which is an agate of variegated white and brown colour, also convex and horizontally perforated, we see a much more artistic intaglio work, representing a Hera-idol, in the form of a cow-head, with two long horns, in perfectly faithful imitation of nature. Between the two horns we see, head downward, an ornamented double-edged axe, with its handle, the extremity of which is ornamented with two rings or turned buttons. To the right and left of the cow-head we see a beautifully ornamented object, the nature of which we are unable to explain; it resembles a cornucopiæ. I remind the reader that this lentoid gem, as well as the other with the two horses, was found close to the ancient Heræum, of which the foundations, consisting of various courses of Cyclopean masonry of enormous uncut blocks, still exist, and may be as old and even older than the walls of Mycenæ and Tiryns. But my explorations on the site, in February, 1874, have shown that the accumulation of _débris_ there does not exceed 1½ to 3 ft. in depth, and consequently excavations there are impossible. The ancient Heræum was accidentally destroyed by fire in 423 B.C., and its site has remained deserted, the new Heræum being built on the slope, about 50 ft. below the ancient one.
