The statue of Zeus, which has already been mentioned as made by Theokosmos for Megara (p. 92), appears to have been made from a clay model. It was intended to be of gold and ivory, but the breaking out of the Peloponnesian War prevented the artist from carrying out his intention, and only the head was completed, the other portions being of gypsum and terracotta. At a later period gypsum was sometimes used for sculpture, as in the case of an Apollo mentioned by Prudentius,[392] and some fragmentary remains from Cyprus in the British Museum. The clay models were sometimes made entirely by hand, but more usually on a wooden core known as κάναβος,[393] which we may conjecture to have been formed of two rods in the form of a cross, from the use of the Latin word _crux_ in this connection.[394] It was certainly a framework, not a solid core, and must be carefully distinguished from κίνναβος, a lay-figure. Aristotle, in an interesting passage, uses the word in speaking of skeletons drawn on a wall.[395] The modelling of details was done partly with tools, partly with the finger. The use of the finger-nail for this purpose became proverbial, as in the saying attributed to Polykleitos: “When the clay has reached the finger-nail stage, then the real difficulty begins.”[396] The chief attention of inferior artists was directed to the production of small terracotta figures, which the Greeks used as ornaments or household gods, buried in their tombs, or dedicated in their temples. They follow the same lines of development as the larger sculptures, beginning with the columnar (ξόανα) and board-like (σανίδες) types found in the primitive tombs of the Mycenaean and early Hellenic civilisation. Originally they seem to have been manufactured purely for religious purposes, but in course of time, with the gradual rationalising of religious beliefs and consequent secularisation of art-types, they lost this significance, and, while the _types_ were preserved, they were converted into _genre_ figures from daily life. These statuettes have been found on nearly all the famous sites of antiquity from Babylonia to Carthage and Kertch; the most fruitful have been Tanagra in Boeotia, Rhodes, the Cyrenaica, Capua and Canosa in Italy, and various sites in Sicily. In Cyprus, Sardinia, and to a great extent also in Rhodes, Phoenician influences seem to have been dominant, and the earlier types bear a markedly Oriental character. For beauty and charm the palm has by general consent been given to the Tanagra statuettes of the fourth and third centuries, which were known in antiquity as κόραι or “maidens,” from the prevalence of the seated or standing types of girls in various attitudes.
