A krater or crater (, kratēr, literally "mixing vessel") was a large two-handled shape of vase in Ancient Greek pottery and metalwork, mostly used for the mixing of wine with water. Form and function At a Greek symposium, kraters were placed in the center of the room. They were quite large, so they were not easily portable when filled. Thus, the wine-water mixture would be withdrawn from the krater with other vessels, such as a kyathos (pl. kyathoi), an amphora (pl. amphorai), or a kylix (pl. kylikes). In fact, Homer's Odyssey describes a steward drawing wine from a krater at a banquet and then running to and fro pouring the wine into guests' drinking cups. The modern Greek word now used for undiluted wine, krasi (κρασί), originates from the krasis (κράσις, i.e., mixing) of wine and water in kraters. Pottery kraters were glazed on the interior to make the surface of the clay more impervious for holding water, and possibly for aesthetic reasons, since the interior could easily be seen. The exterior of kraters often depicted scenes from Greek life, such as the Attic Late 1 Krater, which was made between 760 and 735 B.C.E. This object was found among other funeral objects, and its exterior depicted a funeral procession to the gravesite. Usage At the beginning of each symposium a symposiarch (συμποσίαρχος), or "lord of the common drink", was elected by the participants. He would then assume control of the wine servants, and thus of the degree of wine dilution and how it changed during the party, and the rate of cup refills. The krater and how it was filled and emptied was thus the centerpiece of the symposiarch's authority. An astute symposiarch should be able to diagnose the degree of inebriation of his fellow symposiasts and make sure that the symposium progressed smoothly and without drunken excess. Forms Column krater This form originated in Corinth in the seventh century BC but was taken over by the Athenians where it is typically black-figure. They ranged in size from to in height and were usually thrown in three pieces: the body/ shoulder area was one, the base another, and the neck/ lip/ rim a third. The handles were pulled separately. They were painstakingly studied by archaeologist Tomris Bakır. Calyx krater These are among the largest of the kraters, supposedly developed by the potter Exekias in black-figure style, though in fact
