This vase is one of only twelve all-glyphic vases known to exist. Called “Dynastic Vases,” the vessels recount and date a series of coronations of rulers of the Snake Dynasty, a powerful ruling lineage of the Maya. The exact number of coronations recounted varies depending on the size of the vessel and the scale of the glyphs. The attested range is between five and nineteen, and this vessel provides the second-longest document sequence: twelve separate coronations. As in all societies where lineage served political purposes, the Maya kept dynastic lists of various forms.
