The Origins of Mesoamerican Writing
J Marcus
Annual Review of Anthropology, October 1976, Vol. 5, Pages 35-67

Marcus, Joyce. First dates: the Maya calendar and writing system were not
the only ones in Mesoamerica--or even the earliest. Natural History (Apr. '91)
p. 26-9.

ABSTRACT: Through the contributions of the Maya, hieroglyphic writing
assumed its maximum versatility, complexity, and
correspondence to a spoken language, but the Mayas were not
the first Mesoamericans to use writing and calendars. Both
hieroglyphic writing and calendrical systems originated
among chiefdom societies that ran from the Valley of Mexico
south through the present states of Morelos, Veracruz,
Oaxaca, and Chiapas to the Pacific coast of Guatemala and El
Salvador. The first carved stone monuments with hieroglyphs
were built in Oaxaca, southern Veracruz, and western
Chiapas, which were not parts of the Mayan region. Many of
the early hieroglyphs were based on the 260-day calendar,
which was common to the Mesoamerican chiefdoms that existed
between 2,500 and 3,000 years ago. Monument 3 from San Jose
Mogote in the Valley of Oaxaca is the earliest known stone
carving that displays elements of this calendar. Various
pre-Mayan hieroglyphs and calendars are discussed.


Papers I don't have access to:
Maybe someone else can get them?
