This paper analyzes the reading format and reading order of the recently described Cascajal Block, an artifact with an Olmec-style inscription. The analysis, based not on the iconicity of the signs and their orientation, but solely on the formal and organizational characteristics of the text as a whole, and the patterns of repeated sign sequences, suggests that the text was written from left-to-right, bottom-to-top—if one assumes the orientation assigned to the block by Rodríguez Martínez et al. (2006). However, a simple 90-degree rotation of the block would render the text in left-to-right, top-to-bottom reading format and order—the same as that of later Mesoamerican scripts. It is suggested that the San Andres roller stamp and the La Venta obsidian core, both of which exhibit a pictorial image and an accompanying text, allow for a determination of the relative orientation of text and image with respect to each other, and support the hypothesis for the reading format proposed here. Also, preliminary structural analysis of the text reveals several patterns that are possibly indicative of linguistic structuring, and steps for future work on decipherment are outlined. Finally, the findings are placed within a broader context of previous studies of Olmec writing.
