This was the then unknown Relation de las cosas de Yucatan, and the information on the Maya calen dar and writing that it contained proved vital toworking out a chro nology for this ancient civilization. men Three share the principal credit for this achievement. One was a field archaeologist, Alfred Maud slay, who between 1883 and 1894 made numerous expeditions toMaya sites, bringing back a superb photo graphic record as well as molds of inscriptions and sculptures (Fig. 1). His work, published in the Biologia Centrali-Americana between 1889 and 1902, is still invaluable to ar chaeologists today. The second per son was Ernst F?rstemann, Royal Li brarian of Saxony and custodian of the late pre-Hispanic Maya book known as the , one of only three surviving codices and the to key understanding Maya obser vations of the moon and Venus as well as the place-notation mathe matics used in Maya astronomical calculations.

Surveys of the central lowlands of the Rio Bee zone in the ; late 1960s and early 1970s revealed ; large areas of terracing intersected by I field walls (Turner 1974). An impor tant characteristic was the shallow ness of many of the slopes. The walls were not strictly necessary to counter erosion or to trap silt, as in theMaya Mountains, but were used to form permanent divisions of the terrain. Small farmsteads were included in the field pattern, which appears to be farmore organized than a milpa cycle would justify: continuous cropping under some kind of rotation system with short fallow periods seems much more plausible. The Rio Bee fields date mainly from the Late ^^^^^^^^^^^^^^^^^^^^^^^ii^^i Classic period, but Healy and his co- j workers (1980) have suggested that ! an earlier use of terracing occurred i on the western side of the Maya Mountains from the Late Formative to the end of the Classic period, peaking in the Early Classic period.
