The _wave-pattern_ or kymation moulding, shown in Fig. 149, is one which constantly occurs in Greek architectural decoration, but on the vases at any rate seems to be found only at a late period. On the Campanian vases it is the regular border below the design; it is also found on those of Lucania and Apulia. The _crescent_ is only found on early Ionic vases, including those which have been attributed to a Samian origin (Vol. I. p. 336 ff.), and some of the Daphnae and Naukratis fragments, which probably borrowed it from Samos; it is arranged in bands alternating in colour, black or purple and white. Another typically Ionic ornament is the _scale-pattern_, which occurs on many of the so-called Rhodian vases, and also on those from Daphnae (Fig. 150). In the former it is produced by means of incising on the black varnish, the alternate scales being often coloured purple; but in the latter it is painted in outline. Curiously enough, it also occurs in the incised form on an early group of Corinthian vases (Plate XIX. fig. 3). Like other patterns, it can be traced to a Mycenaean origin, being very common in that style. Subsequently it occurs but rarely, but is sometimes employed on the neck or shoulder of a vase.[2028] It differs from most other patterns in that it does not lend itself to the panel or frieze, but covers a surface of indefinite extent. It is also known as the “imbricated” pattern, from its likeness to overlapping tiles (_imbrices_). [Illustration: FIG. 151.
