Flute-playing was very popular with the Romans, among whom it was considered the proper accompaniment of every kind of ceremony.[97] For military purposes they used several other wind instruments. Two bronze mouthpieces (No. =649=) in Case 55 may perhaps come from long straight trumpets (_tubae_). The Roman curved horn (_cornu_) is represented by two large specimens in bronze (No. =650=) placed at the top of Cases 55, 56. The terracotta bugle in Case 55 is probably a model of the Roman _bucina_ (No. =651=). [Illustration: FIG. 254.--BRONZE FLUTES AND CYMBALS (NOS. 646, 654). 1:3.] The simplest of all ancient wind instruments is the rustic Pan's pipe (_syrinx_), usually formed of seven or eight hollow reeds fastened together with wax. The Greek Pan's pipe has the reeds of equal length, the different notes being produced by the different positions of the natural joints of the reed. An example may be seen among the Cypriote sculptures in the Gold Ornament Room passage. The Roman _syrinx_ had its lower edge sloping, the result of cutting off the reeds immediately below the natural joints. A terracotta statuette in Case 55 (No. =652=) represents a shepherd boy playing on a Pan's pipe of the Roman kind, and a marble relief from Ephesus at the top of Case 54 (No. =653=) shows a beardless man seated with a large _syrinx_ in his hands. The Greek inscription tells us that the relief was dedicated by Ebenos, a "first flute," to Hierokles his piper. It was the Pan's pipe which gave Ktesibios of Alexandria (third century B.C.; cf. p. 120) the model on which he constructed his water-organ, an instrument which became popular with the Romans. A Roman "contorniate" shown in Case 58 has one of these water-organs represented upon it. The air was supplied by water pressure and the notes were played by means of a key-board. Cymbals were largely used by the Greeks and Romans in religious ceremonies of an ecstatic character, such as the mysteries of Demeter and Kore and the worship of Kybele. Among the cymbals in Case 56 is an interesting pair (No. =654=; fig. 254) inscribed in Greek with the name of Oata their owner ([Greek: Oatas eimi]). They were originally joined together by a chain, part of which still remains. In the lower part of Cases 55-56 is a considerable variety of bells in bronze (No. =655=).
