Note on Correlation and Orthography
I make use of the generally accepted original correlation of Goodman- Martinez-Thompson (GMT) 584, 283 for the conversion of the classic Maya Long Count calendar into the Gregorian calendar.
The transcription of the inscriptions is set in bold types. Logographs are expressed in capitals; syllables and vowels are rendered in lower case. The transliteration is set in lower case and in italics.
In 1988 Maya scholars in Guatemala established the Academia de las Lenguas Mayas de Guatemala (ALMG). One of the organisation’s most important contributions was the reform of the orthographies of the Mayan languages by Indigenous linguists. For instance, “Popol Vuh” is spelled “Popol Wuj” and “Cakchiquel” is written “Kaqchikel” according to the new official orthography. I will follow the orthography established by ALMG when it comes to the spelling of the classic Maya inscriptions. Conversely, the orthography of the Yucatec colonial sources will be applied in the analysis of the rituals of the postclassic Yucatec 260-day calendar and 365- day calendar.
The calendar names of the classic Maya for the 365-day calendar are rendered in classic Maya, as reconstructed by Wichmann (2000a). The 260- day calendar of the classic Maya is kept in Yucatec because the correct pronunciation of the day names is not known.
I prefer using the term “veintena” (“score”) to “month” when designating the 20 day units of the Mesoamerican 365-day calendar.
I have employed the Nahuatl translation of Fray Bernardinho de Sa- hagun’s Florentine Codex by Charles E. Dibble and Arthur J. O. Anderson (1950 - 1982) and Primeros Memoriales by Thelma D. Sullivan (1997) into English. Quotations from Sahagun into Nahuatl follow Dibble and Anderson and Sullivan’s orthography.
