the finished drums waiting to be transported. Along with the column drums, there are also some capitals and also square incisions for quarrying square blocks, all intended for the temples of Selinus. Of the drums that had already been extracted, some were found ready for transport and others, already on the way to Selinus were abandoned on the road. Some gigantic columns, definitely intended for Temple G, are found in the area west of Cave di Cusa, also in the state in which they were originally abandoned. Coinage The coins of Selinus are numerous and various. The earliest, as already mentioned, bear merely the figure of a parsley-leaf on the obverse. Those of somewhat later date represent a figure sacrificing on an altar, which is consecrated to Aesculapius, as indicated by a cock that stands below it. The subject of this type evidently refers to a story related by Diogenes Laërtius that the Selinuntines were afflicted with a pestilence from the marshy character of the lands adjoining the neighboring river, but that this was cured by works of drainage, suggested by Empedocles. A figure standing on some coins is the river-god Selinus, who was thus made conducive to the salubrity of the city. The Seal of the London School of Hygiene & Tropical Medicine is based on a coin of Selinus struck in 466 BC which was designed by the sculptor and medallist Allan Gairdner Wyon FRBS RMS (1882-1962). It shows two Greek gods associated with health - Apollo, the god of prophecy, music and medicine, and his sister Artemis, goddess of hunting and chastity, and comforter of women in childbirth - in a horse-drawn chariot. Artemis is driving while her brother the great archer is shooting arrows. The fruitful date palm was added to indicate the tropical activities of the School but also has a close connection with Apollo and Artemis: when their mother Leto gave birth to them on the island of Delos, miraculously a palm sprang up to give her shade in childbirth. Asclepius, Apollo's son, was the god of ancient Greek medicine, and was frequently shown holding a staff entwined with a snake. Snakes were used in this healing cult to lick the affected part of the patient. Significantly Asclepius' daughters were Hygeia (the goddess of health) and Panacea (the healer of all ailments). Asclepius' staff with a snake coiled round it (known as a symbol
