The brick date does coincide with the end of the 13th Baktun; Baktuns were roughly 394-year periods and 13 was a significant, sacred number for the Mayas. The Mayan Long Count calendar begins in 3114 B.C., and the 13th Baktun ends around Dec. 21, 2012.
But the date on the brick could also correspond to similar dates in the past, Stuart said.
“There’s no reason it couldn’t be also a date in ancient times, describing some important historical event in the Classic period. In fact, the third glyph on the brick seems to read as the verb huli, “he/she/it arrives.”
