The dying Alexander: “‘The Dying Alexander’, at Florence. This well-known, beautiful, and deeply affecting head, which bears a strong resemblance to the Alexander Helios of the Capitol --especially in the treatment of the hair--has been called by Ottfried Mueller a riddle of archaeology. It is no doubt a Greek original, and one of the most interesting remains of ancient art, but we cannot take it for granted that it is intended for Alexander, and still less that it is the work of Lysippus. It is difficult to imagine that the favored and devoted artist of the mighty conqueror would choose to portray his great master in a painful and impotent struggle with disease and death. This consideration makes it extremely improbable that it was executed during the lifetime of Alexander, and the whole character of the work, in which free pathos is the prevailing element, and its close resemblance in style to the heads on coins of the period of the Diadochi, point to a later age than that of Lysippus.” --‘Greek and Roman Sculpture’ by Walter Copland Perry.
