This cylindrical drinking vessel records a number of hunters returning from a successful hunt. If we roll out the scene, we see that there are two individuals who are carrying deer on tumplines hanging right from their very foreheads.
Other individuals are blowing on conchshell trumpets, indicating the return of successful hunters from their foray into the wilderness. Intriguingly, hieroglyphs above the scene are not actually legible.
They're what scholars refer to as pseudo-glyphs, illegible writing provided to give the idea of writing, and to channel the prestige of writing from the center of the Maya world into texts that are recorded on the outskirts of Maya civilization, where perhaps a very different Maya language was actually spoken.
