This is a fairly typical Hellenistic pottery vessel. It broadly falls into the “unguentarium” type, so called because such vessels were commonly used for holding scented oils prior to the invention of glass blowing, after which they were quickly replaced by cheap blown glass in the Roman period. This example is a squat version of the type and could have been made in Eastern Mediterranean between about 300 and 50 BCE. Condition is good for age.
Item comes from the Estate of a country doctor who practiced in rural upstate New York.
