What it is

A stela bearing a long inscription of about 465 glyphs and a Long Count date equivalent to AD 156, in the epi-Olmec or Isthmian script. It is the longest known text in that script.

Justeson and Kaufman's 1993 decipherment, reading it as a Mixe-Zoquean language, is disputed by other researchers.

What it led to

  • knowledge of the Long Count outside the Maya area
  • a long text for studying a possible Olmec-Maya bridge
  • attempts to decipher the Isthmian script
