This conception was fundamentally different from that of the modern scientific mentality.” Johanna Broda, 19822 “The results of the present work [in Oaxacan archaeoastronomy] show that the Zapotecs, while participating in pan-Mesoamerican orientation principles, used their own orientation, also based on calendar properties. For example, they erected buildings that simultaneously synthesized several of these orientations. This [synthesis of pan- Mesoamerican and Oaxaca-specific astro-calendrical principles] was a remarkable innovation that demonstrates the subtle genius of the Zapotecs, who, as insightful observers of nature, chose this peculiar form of cult to the continuity of time, with which they ingratiated themselves with the gods who had granted a benefit as precious as the calendar.” Jesús Galindo Trejo, 20083 * Note that I have managed the footnotes in ways that respect “the first citation” (which is thus a full bibliographical citation) in this chapter, irrespective of whether that work was cited in a previous chapter. Also, to avoid confusion in this typescript, I have retained the quotation marks on all quotes, including those that are formatted as block quotations. 1 Mircea Eliade, Patterns in Comparative Religion, trans.

Chapter 3: “Orientation via Astronomically-Aligned Architecture (priority I-C);” p. 338 This chapter is devoted to asking and answering the question: How and to what extent is the so-termed astronomy priority (I-C) relevant to the orientation and religion of Monte Albán? Recall that, as outlined in The Hermeneutics of Sacred Architecture, I use “astronomy” to refer in the broadest strokes to ritual-architectural configurations that are aligned or referenced with respect to celestial bodies—the sun, moon, planets or stars.4 Of the eleven main priorities in my morphology, the cross-culturally comparative relevance of this one is the most uneven insofar as alignments with respect to sky phenomena play no role whatever in many religious architectures while, in others, purposeful astronomic references are a matter of intense importance. Pre- Columbian Mesoamerican architecture, as we’ll quickly see, is among the latter. This is an ambience in which the abundance of open-air ceremonial precincts is, perhaps without exception, configured in ways that afford natural celestial phenomena a prominent place in the choreography of periodic ritual-architectural events.
