In a presentation in 2007 at the Denver Art Museum, I suggested the possibility that an artistic theme referred to in Maya archaeology as the Charlie Chaplin figurine theme for most of the past century had diffused from the Maya region to the Chibchan area of ancient Costa Rica (Mora-Marín 2007). The idea developed further, eventually coming out as an article in Cuadernos de Antropología in 2016 (Mora-Marín 2016). Figure 1 illustrates the basic point-for-point correspondences between the Mayan-style figurines (Figures 1A and 1C) and the Chibchan greenstone pendants in question (Figure 1B). No one iconographic element or motif is obligatory in the Mayan version, but the most common ones are the sideways-pointing feet and the arms-bent-at-elbows components (Traits 2 and 4).
Figure 1. Comparison of Mayan Ritual Specialist Theme with Chibchan counterpart.
I proposed, based on the available dates, that the Mayan theme, itself a local variant of a pan-Mesoamerican theme that can be traced back to Olmec art in the Middle Preclassic (1000–400/300 BCE) period, with examples dating to as early as the end of the Late Preclassic (400/300 BCE-CE 200) period, served as the inspiration for the Chibchan Ritual Specialist Theme, whose earliest examples are not well dated, but may start around CE 100–500. I proposed that the two represent the same idea: a Ritual Specialist Theme.
Figure 2 shows how the Chibchan artists adapted the theme, either in its plain form (Figure 2A), or with elaborations based on local artistic motifs and themes (Figures 2B–C), such as the double-zoomorphic motif on top of the head (Figures 2B–C), sometimes shown as avian and other times as reptilian, as well as the occasional addition of miniaturized trophy heads (Figure 2C) and reptilian feet (Figure 2C).
Figure 2. Examples of Chibchan Ritual Specialist Theme with and without local elaborations.
I also proposed that this borrowed Ritual Specialist Theme influenced the development of new themes or subthemes in the Chibchan artisan’s repertoire. Figure 3 illustrates the possibility —raised in that same paper— that the Mayan theme (Figure 3A) may have inspired not only the Chibchan version of the Ritual Specialist Theme (Figure 3B), but also the evolution of the Chibchan Anthropomorphic Celtiform Pendant Theme (Figures 3D–E) as a result of convergence or conflation of the earlier Chibchan Avian Celtiform Pendant Theme (Figure 3C) and the Chibchan Ritual Specialist Theme (Figure 3B). Moreover, as also seen in Figure 3, I suggested that the Chibchan avian celtiform pendant theme, which had appeared already around 500 BCE in the Pacific Northwest of Costa Rica, combined with the new Ritual Specialist Theme, led to the creation of the anthropomorphic celtiform pendant theme.
Figure 3. Development of Anthropomorphic Celtiform Pendant from conflation of Ritual Specialist and Avian Celtiform Pendant. 
In other words, there is now reasonable evidence that there was diffusion of information —artistic, ideological— between the two regions, the Maya region and the Chibchan region of ancient Costa Rica, more specifically. It is also evident that this artistic theme in turn influenced local artistic developments. This was not an isolated phenomenon: it was no doubt a consequence of the interregional interaction network of exchange in preciosities, involving jadeite and other greenstones, ceramics, and likely other types of items, such as Spondylus shell, among others. Such exchange was responsible for the arrival and ultimate deposition of Chibchan-style jade pendants from Costa Rica at Maya sites (in royal burials and cosmopolitan caches), and Mesoamerican-style (Olmec, Teotihuacan, Zapotec, Mayan) artifacts in Costa Rica, including several dozen whole or fragmented Mayan royal jade belt plaques (e.g. Reents-Budet and Fields 1991; Fields and Reents-Budet 1992; Mora-Marín 2002, 2008; Reents-Budet et al. 2016, 2018; Mora-Marín et al. 2018).
The present note raises the possibility of another example of iconographic diffusion, possibly as a simple motif, but perhaps, at times, as a more comprehensive theme. I initially thought of this new case after John Hoopes raised the possibility of the two of us co-authoring a paper on the topic of interaction between Mesoamerica and Isthmo-Colombia, following his participation in the 10th European Maya Conference in 2005, with the theme “The Maya and Their Neighbours – Internal and External Contacts Through Time.” In the end, however, many factors conspired against our collaboration, and we were not able to contribute to the proceedings volume. I then thought some more about the case, and gathered a few examples, and presented them in public on my own (Mora-Marín 2016b, 2021), and with my colleague Dorie Reents-Budet 2021 (Mora-Marín and Reents-Budet 2021).
This new case can be referred to as a “Transformation” motif because of its function in ancient Mayan writing, and some of its associations in the Chibchan art from Costa Rica. I should note that not all cases of its occurrence in Mayan art have been studied, and as a result, its meanings and functions in artistic contexts are not yet known; similarly, the range of contexts in Chibchan art also shows great variation, so that it is not possible to know with great certainty whether it conveyed the same meaning or had the same function in all cases. The sign in question is ZS5/T645, which depicts two interlocked bands or a single twisted band, sometimes showing a series of dots or spots, as seen in Figure 4A, and only partially, as explained next, ZAD/T539, which depicts a face partially covered on one side with jaguar skin/pelt, is seen in Figure 4B. They appear to be allograms: each one is a logogram, a sign representing a lexeme or word, and they both bear the same value, WAY for Ch’olan *wäy ‘co-essence’ (Houston and Stuart 1987), and in some cases seemingly related to the notion of ‘shape-shifter’ as well. There are other signs in Mayan writing that may also be allograms with this same value, but they are not relevant to the problem at hand. (There is another Mayan grapheme that appears to be graphically related to ZS5, but bears a different value: YS5/T676 TAL. A future note will discuss these graphic relationships and explore possible semantic and contextual associations between the different values.)

As Figure 5 shows, the two signs briefly overlap during the Early Classic (CE 200–600) period, but it appears that ZS5 was the more common of the two during that time period, with dated examples bearing a mean date of 433.6. Nevertheless, ZAD had replaced ZS5 before the end of the Early Classic period, and was the most common allogram by far with the value WAY for *wäy ‘co-essence; shape-shifter’ thereafter, showing a mean date of 727.1.

Figure 6 shows a few examples from actual texts. Importantly, note that ZS5 can include a line that spans at least part of the length of the interlocked bands or single twisted band (Figures 6A and 6E), in addition to dots or spots (Figures 6A–D), or just the line dividing the interlocked bands or twisted band (Figures 6D–E). Also, note that some cases show a transition from a simple ZS5 to ZAD (Figures 6D–E), showing the partial covering with jaguar skin/pelt; Figure F shows an example of ZAD, which is composed of half of ZA1/T533 on the left side and half of a jaguar skin/pelt. The apparent transition supports the notion that ZS5 and ZAD were in fact allograms, signs bearing the same value.

For the present purposes, the sign that matters is really only ZS5, the sign depicting either two interlocked bands, or a single twisted band. It is this allogram that can be connected to the Chibchan motif seen in Figure 7. Note especially the example in Figure 7C, showing the line dividing the dots or spots (cf. Figures 6A–C), as well as the line spanning much the length of the bands (cf. Figures 6A and 6C).

In fact, in Mayan art and writing, it appears that ZS5 (Figure 8A) is a simplified or abbreviated version of an iconographic motif involving two interlocked bands (Figure 8B), attested on a polychrome vessel housed at LACMA, as observed by Dorie Reents-Budet (personal communication, 2021). This version is graphically identical to some versions of grapheme YS5, which bears the logographic TAL. Previously, John Hoopes (personal communication, 2005) had suggested a connection with a symbol appearing in the Codex Mendoza in association with silver smithing, while Dorie Reents-Budet (personal communication, 2021) also observed its presence on an Aztec jade head (Coyolxauhqui sculpture) where it serves as a tag on a representation of a gold bell. It is possible the that common theme among these uses of ZS5 has to do with “transformation.”

Grapheme ZS5 is attested in at least one Mayan jade pendant recovered from Costa Rica, a fragment of an Early Classic royal belt plaque in the Metropolitan Museum of Art collection, seen in Figure 9. This example shows ZS5 atop a grapheme depicting a SKULL, possibly for JOL or B’AK, itself atop a grapheme resembling the syllabogram so. Together these three graphemes likely spell a glyphic name of a ruler, likely embedded in the headdress of a portrait of said ruler, though this cannot be determined for sure. Thus, ZS5 can be shown to have been seen by Chibchan artisans. (So was YS5/T676 TAL, the grapheme mentioned above to be graphically related to ZS5. YS5/T676 TAL is also attested in an Early Classic Maya royal jade belt plaque reported from Costa Rica.)

Also it is worth noting a possible association with transformation, specifically with shape-shifting. John Hoopes (personal communication, 2005) noted that the Galo Polychrome “man” (Figure 10A) shows evidence of reptilian traits, perhaps crocodilian specifically (Figures 10B–C). Hoopes (2004, 2007, 2023) has discussed the evidence —ethnohistorical and archaeological— for the concept of therianthropic transformation of shamans, in particular, in the Isthmo-Colombian region, including the Chibchan peoples of Costa Rica. Hoopes and Mora-Marín (2009:309–313) have also offered some comparative remarks on therianthropic transformation and its representation in both Chibchan and Mayan art.
Figure 10. Galo Polychrome effigy vessel from Museo Nacional de Costa Rica.
On the effigy’s back (Figure 11), we see one of the interlocked band motifs already illustrated (Figure 7D). Thus, this shows an association between the motif and the notion of transformation, or at the very least, of an association with some sort of crocodilian alter ego or co-essence.
Figure 11. Back of Galo Polychrome effigy vessel from Museo Nacional de Costa Rica showing Chibchan version of ZS5.
Another example, seen in Figure 12, consists of a Galo Polychrome effigy vessel in the shape of a jaguar, though one that suggests a human pose. It also bears an elaborate version of the intertwined motif on its back.

Examples also appear in association with bat imagery; there is ample evidence for associations between ritual specialists and bats in Chibchan art across several media (e.g. jade and ceramic). Figure 13 illustrates an example.
Figure 13. Guinea incised effigy vessel (bat) from Museo del Jade with ZS5 as motifs on wings.
The motif appears also on stone metates, like the example seen in Figure 14. The metate is carved partly in the shape of a macaw, once again suggesting an association with animal transformation or co-essences. This type of metate has been estimated by Chaves Chaves and Fontana Coto (1993) to date to ca. CE 300–700.

The motif is also found in contexts where there is no obvious connection to the concept of animal transformation or co-essences. Figure 15A shows an instance incised on the pronounced belly of a female Guinea incised effigy vessel. Figure 15B isolates the motif, already illustrated in Figure 7C. It can be compared to Mayan ZS5 in Figure 15C. Perhaps the transformation of interest here has to do with pregnancy and birthing.
Figure 15. Guinea incised effigy vessel from Museo del Jade.
Figure 16 provides similar examples on another female Guinea incised effigy vessel, bearing the example of the motif already illustrated in Figure 7E.
Figure 16. Guinea incised effigy vessel from Museo del Jade. 
Figure 17 provides an example of the motif, already illustrated in Figure 7A, on the back of a Carrillo Polychrome effigy head vessel. Though there is no obvious connection to any kind of transformation or animal co-essence, perhaps the motif marks the portrayed individual as a person who had the power to shape-shift.
Figure 17. Carrillo Polychrome vessel.
Figure 18 shows two more Carrillo Polychrome effigy head vessels, this time showing the motif in question on the head’s cheeks.

Finally, Figure 19 shows an example of a ceramic stamp from the Museo del Jade, probably the exact same device used to apply the motif on a person’s cheek.

The case at hand is also interesting because it can be suggested that the direction of diffusion was the reverse of the Ritual Specialist Theme: from the Chibchan area of Costa Rica to the Maya region. This is supported, tentatively, by chronology: Table 1 shows the temporal ranges for the earliest ceramics where this motif is attested.
Table 1. Temporal ranges of ceramics with early attestations of “Transformation” motif.
It is quite possible, based on these temporal ranges, starting as early as 300 BCE and 100 BCE, that the Chibchan version of the motif preceded the Mayan version, ZS5, which is so far attested in dated texts only as early as the fourth century. However, a version of ZS5 may be attested in at least one Late Preclassic inscription, Kaminaljuyu Monument 10, the subject of a future note. But at the very least, it seems like this is another possible case of interregional diffusion between Mayan and Chibchan societies.
