This bottle belongs to a small group of similar vessels that were probably made in a workshop at Cologne, a major Roman city on the River Rhine, where at least one example has been found. Their function remains uncertain, and their practicality as containers is doubtful. In all likelihood, they were primarily decorative. The vessel shown here is unusually large, with delicate trails of opaque blue glass wound around the body at both ends.
