A Byzantine earthenware hand grenade shaped like an acorn. The vessel features a round knob neck with a small opening, a hollow bulbous body decorated with vertical grooves at the top and a pointed base. The mouth allowed the item to be filled with incendiary liquids to be used in battle and would have also accommodated a fuse to instigate the explosion. As is typical for Byzantine grenades, this piece displays a deep incised band used to help with grip.
