 Some signs can be recognized as calendar information but the script as such remains undeciphered.Read in columns from top to bottom, its execution is somewhat cruder than that of the later Classic Maya and this has led epigraphers to believe that the script was also less phonetic than the largely syllabic Mayan script.The earliest known artifact with Zapotec writing is a "Danzante" ("dancer") stone, officially known as Monument 3, found in San Jose Mogote, Oaxaca.
