It is worth while to give this emblem some little study. It is represented under three varieties of one general form. We first find it a bundle of flames wreathed closely together in the form of a double cone. It is then a token of peace. Zeus is always seated when bearing this, and it is held downward. Under its second form the thunderbolt consists of a similar double cone, only it is elongated and pointed. This cone is crossed obliquely by two zigzag flashes of lightning, terminating at either end in arrow-points. Later forms of this symbol have the forward end the same, but the other end is wrought into an ornamental and somewhat arborescent head. This form with the lightning flashes is always borne uplifted, and by the god standing in readiness to hurl the bolt. This is the form we are to look for in connection with the worship of Zeus. The third form is of rare occurrence in literature and art. Another emblem of the Olympian god, more familiar even than the thunderbolt, is the eagle. Æschylus calls this bird "the winged hound of Zeus." This conception of the poet ruled in art as well as in literature. It was the popular idea of divine vengeance following and punishing guilt that sought concealment. Open impiety drew down upon the offender's head the flashing thunderbolt. A comparative examination of a few coins will help towards interpreting this symbolism. For this purpose the coins of Elis will serve best. Here was Olympia, with its famous temple of Zeus, and here were celebrated the great national Olympian games in honor of the god. Certainly if any part of Greece was more sacred to Zeus than the rest, that part was Elis. Its coins are covered with his symbols. Three types of about 371 B.C. form a group of especial interest. The first of these has, obverse, an eagle tearing a ram, on a shield; reverse, a thunderbolt. Second, obverse, an eagle tearing a serpent; reverse, a thunderbolt. Third, obverse, an eagle tearing a hare; reverse, a winged thunderbolt. Here the identity is sufficiently close to bring these examples under one description. They seem to commemorate the just punishment of some enemies of Elis, or, possibly, the deserved penalty for some wrong done Zeus himself. It would not be easy at this late day to make sure what people or persons may have been indicated by the ram, the serpent, and the hare. The obverse in each case tells the story of the event so far as we can read the story, and the reverse invariably confirms the tenor and spirit of the same. This harmony between the two sides of the coin may be traced throughout ancient coinage, proving that it was of a medallic character. Other coins of Elis are of a peaceful character, and it is of interest to see how the emblems are managed upon these. One has, obverse, head of eagle; reverse, thunderbolt within a wreath. Another, obverse, head of Hera; reverse, eagle standing in wreath. A third, obverse, head of Olympia; reverse, eagle within olive-wreath.
