A transparent red glass gemel bottle, with applied rigaree, probably dating to the mid-nineteenth century. Gemel bottles consist of two (sometimes more) separately blown glass bottles or flasks fused together, with their necks curving in opposite directions. Each chamber would hold a different liquid, often a pair that would commonly be used together such as oil and vinegar. Other gemel bottles were intended to hold various liqueurs, or even perfumes. The word gemel comes from the name Gemini, who in ancient Greek and Roman mythology were semi-divine twins named Castor and Pollux.
This gemel bottle was found in a pantry in the Longfellow house when the National Park Service took over the site in 1972.
