Lentoid Aryballos (Container for Oil) c. 4th century

This small, ancient glass vessel, dating back to the 4th century, is an example of a lentoid aryballos. These small containers, often used for oils, were popular throughout the Eastern Mediterranean. The intricate, swirled design on the aryballos, achieved through a technique called "diptych" glassmaking, features contrasting shades of blue, white, and yellow. The "diptych" method involves fusing two layers of glass together and then shaping the vessel while the glass is still malleable. This piece, currently on display at The Art Institute of Chicago, showcases the sophisticated glassmaking techniques of the ancient world.
