Old Notes on /jo/ and /wo/ Reply

Way back in 1987 Steve Houston wrote me with some important insights about a hieroglyphic sign found from time to time in the Dresden and Madrid Codices and in the monuments of the Classic period (Figure 1). Early Maya epigraphers such as Benjamin Lee Whorf and J. Eric S. Thompson had long assumed this was a  word-sign for hax, “to drill,” based on the images of fire-drilling that accompanied its appearances in the codices. Most scholars accepted this rather iffy reading until Steve’s important realization that the sign was instead a CV syllable for ho, as in the spelling ho-ch’o and ho-ch’a for hoch’, another verb root in Yucatec meaning “to drill.” (Years later this reading would be refined to jo, reflecting the key distinction made in Classic Mayan between /h/ and /j/ – a contrast that was lost historically in colonial and modern Yucatec [Grube 2004]) . In the summer of 1987, after some days exploring sites and museums in Yucatan, I struck up a correspondence with Steve about a few new and exciting patterns I had seen involving his new jo sign.  These appeared to solidify the reading beyond any doubt. Soon his thoughts on jo made their into print in the journal Antiquity, discussed within his larger article of phoneticism in Maya writing (Houston 1988).


Figure 2.  u wojool, “the glyphs of…”

Building on Steve’s ideas, I posited that the jo sign might help to explain a common hieroglyph found in the texts of the Puuc region, u-?-jo-li, evidently a possessed noun based on a root Coj (Figure 2). My notes of that time explored how an unknown sign before Steve’s jo appeared elsewhere with the possible value wo, suggesting u wojool (or as I then wrote it, u uohol), “the writing, hieroglyph of…”  This reading came to pan-out nicely, and in the texts of Yucatan and northern Campeche it appears in reference to the hieroglyphic decoration on certain architectural features such as jambs and door lintels (Maya texts can be strangely self-referential in this way).

My notes also touched the possibility that jo could explain a title that appeared on Stela 19 from Dzibilchaltun, Yucatan, reading ti-jo AJAW? (Figure 3a).  This seemed to me to be an emblem glyph for the local ruler, and a Classic use of the historical name of nearby Merida, T’ho or Tiho. The idea was particularly exciting to me at the time (and still is), as it suggested a rare case of a historical place name traceable back to the Late Classic period. Later finds at Dzibilchaltun produced better examples of this emblem title, as on a beautiful bone object excavated by the INAH project directed by Ruben Maldonado (Figure 3b). We now know that this local emblem presents a more complex term incorporating another glyph, as in ?-KAAN ti-jo, a sequence that is surely related to the elaborated name of ancient Mérida known from colonial sources Ichcaansiho’. Dzibilichaltun was perhaps an early political and ritual center that was later moved to present-day Mérida, also the site of a very large ruin at the time of the conquest.

At any rate, shown below are my hasty notes from July 31, 1987 and then a letter to Steve Houston of a month later (where I also posit confirmation of the common NAL sign reading, which came into play in our collaborative work on Classic place names).  My school work took over that fall and I never got to publish on u-wojol and the glyph for the ancient name of Merida, Tiho. So here it is.
