We thank Bruhns and Kelker for articulating several issues that others have raised concerning the Cascajal block and for providing us the opportunity to lay them to rest.
1) The provenance of the block is what it is, reported by nonarchaeologists but still fixed to an area of a few square meters within a known archaeological site in Veracruz, Mexico. Many other bona fide examples of ancient writing have even less secure find spots, including every known example of Mesoamerica's Isthmian Script and Egypt's Rosetta Stone. Such objects will continue to appear in the future, and each will require careful study for evidence of reliability. We have done this to the extent of our ability with the Cascajal block and stand by our considered and, to most scholars, valid assessment that it is a key addition to the corpus of inscriptions in Mesoamerica.
2) The authors claim that “[t]he heartland Olmec did not build in stone; therefore, it cannot be an architectural inscription.” Then, in their next sentence, they cite precisely such architectural ornaments at the Olmec site of La Venta. We now suspect that the block may have served such a function. Such texts, especially from coastal Veracruz and the Maya region, characteristically are executed in shallow lines. Indeed, the celebrated La Mojarra Stela 1, found in circumstances much like those of the Cascajal block, was housed in the Museo de Antropología, Xalapa, for more than a year before anyone noticed the more than 500 glyphs on its face. It took some further time to see that an additional text appeared on its side, this on a sculpture under exceptionally thorough scrutiny (1). Therefore, we would not be surprised to learn that other previously discovered examples went unnoticed.
3) The signs form purposeful sequences; they do not “randomly ‘bunch,’” as Bruhns and Kelker assert. The patterns in the Cascajal text are spelled out carefully in our paper.
4) The block contains signs found on objects with provenance and others that lack it. Some of the latter have been known since the 19th century (i.e., the “Humboldt Celt”) (2). One previously unknown sign (glyph 19) appeared years after the discovery of the block in a secure archaeological context at Canton Corralito, Chiapas, Mexico (3). All known hieroglyphic systems in the world relate to pre-existing iconography or codified symbolism; new signs appear when warranted by scribal needs. Any hieroglyphic system that deviated from local iconography would be not only unique but, indeed, an inexplicable phenomenon.
5) If the “insect glyph” was a practical joke, the jokester was an Olmec. The motif is shown three-dimensionally in the diminutive Monument 43 at San Lorenzo, discovered and excavated by one of us (Coe) in 1966 and published by Coe and Diehl in 1980 (4).
We reject the author's specific criticisms and their implicit claim that the block is a modern forgery. However, we appreciate the fact that such challenges are the essence of scientific enquiry and that they eventually lead to truth. We still affirm that the Cascajal block is the oldest example of writing in the New World and among the most important finds ever made in Mesoamerica.
