“…The embedded God C-like face on the toad's torso could be explained by a Mayan linguistic motivation (Central Mayan *k'uʔj “belly, stomach, chest, thorax”), but there is only one example, and thus it is very limited and tentative in nature. The down-turning basal motif, with its clear iconographic connection to the Epi-Olmec syllabogram na, and its likely motivation based on Mixe-Zoquean *naas “earth, land” (Stross 1990; Mora-Marín 2001a, 2003) or Mixe-Zoquean *nɨɨʔ ‘water’ (Lacadena García-Gallo 2010b), is a clearer case; however, this iconographic usage occurs also at Kaminaljuyu, and as Stross (1990) and Mora-Marín (2001a, 2003) have argued, it was probably borrowed into Mayan with its phonetic value, and possibly also its iconographic value. Given this possibility, one could argue that perhaps it was at Izapa where such diffusion occurred.…”
