The Portly Lords of Calakmul: Stelae 51 & 89
"A series of monuments on its frontal (western) terrace include Stela 51 [left], portraying Ruler 7. When Morley recorded it, this was the best-preserved of Calakmul's sculptures, but in more recent times it was sawed into small blocks by looters. Fortunately, the blocks were recovered, and the restored monument is today in the Museo Nacional de Antropología in Mexico City.
A worse fate has befallen the other monuments: Stela 89 [right], for example, once stood at the top of the Str. I stairway, but only a few discarded blocks remain there now, the rest having been hauled off to parts unknown to be sold. "
