Ca. 800-1000 AD. An acorn-shaped ceramic vessel with a tapered base and broad top with a small spout which probably would have been filled with explosive liquid. The shoulder of the vessel is adorned with decorative roundels, creating an aesthetically pleasing appearance. These vessels were designed to be thrown by hand or launched via catapult, and their main purpose was to ignite and spread fire on enemy ships. The precise design of the vessel allowed it to be thrown accurately and to maximize the spread of fire upon impact. The use of these vessels was a critical component of Byzantine naval tactics and played a significant role in their military successes.
