almost always seen in red. The lower body is shaped like the calyx of a flower, and the foot is stepped. The psykter-shaped vase fits inside it so well stylistically that it has been suggested that the two might have often been made as a set. It is always made with two robust upturned handles positioned on opposite sides of the lower body or "cul". Volute krater This type of krater, defined by volute-shaped handles, was invented in Laconia in the early 6th century BC, then adopted by Attic potters. Its production was carried on by Greeks in Apulia until the end of the 4th century BC. Its shape and method of manufacture are similar to those of the column krater, but the handles are unique: to make each, the potter would have first made two side spirals ("volutes") as decorative disks, then attached a long thin slab of clay around them both forming a drum with flanged edges. This strip would then have been continued downward until the bottom of the handle where the potter would have cut a U-shaped arch in the clay before attaching the handle to the body of the vase. Bell krater Bell kraters were first made in the early 5th century, which meant that it came later than the three other krater types This form of krater looks like an inverted bell with handles that are faced up. Bell kraters are red-figure and not black-figure like the other kraters. Metal kraters According to most scholars ceramic kraters imitated shapes designed initially for metal vessels; these were common in antiquity, but survivals are very rare, as the metal was recyclable. Among the largest and most famous metal kraters in antiquity were one in the possession of the Samian tyrant Polycrates, and another one dedicated by Croesus to the Delphic oracle. There are a few extant Archaic bronze kraters (or often only their handles), almost exclusively of the volute-type. Their main production centres were Sparta, Argos and Corinth, in Peloponnesus. During the Classical period the Volute-type continued to be very popular along with the calyx-type, and beside the Corinthian workshop an Attic one was probably active. Exquisite exemplars of both volute- and calyx-kraters come from Macedonian 4th century BC graves. Among them the gilded Derveni Krater represents an exceptional chef d’œuvre of late Classical metalwork. The Vix bronze crater, found in a Celtic tomb in central
