The ancient Greek storage vessel in Hesiod’s Pandora myth was a pithos.
A pithos was a large ceramic container used in the ancient Greek world for storing commodities such as grain, wine, and olive oil. These vessels could be much larger than ordinary tableware and were often kept partly buried or placed in storage rooms.
Hesiod’s Greek text uses the word pithos for the container associated with Pandora. The familiar phrase “Pandora’s box” developed later because translators and retellers rendered the vessel as a box rather than a jar. That translation changed the visual image of the myth but not its central idea.
An amphora was also a storage vessel, but it normally had two handles and a narrower body. A krater was used for mixing wine and water, while a kylix was a drinking cup. Those vessels belong to different categories and are not the container named in Hesiod’s account.
