A nice little overview of a short-lived design style. I don't think Mayan Revival in the United States needs more than a hundred pages or so written about it, frankly. I did find the emphasis on Mesoamerican architecture as the font of a "natively American" aesthetic (for entirely US-American architects) interesting, and there is something theoretically curious in the style's transition from a fantastical theme-park vibe to a "catalog style" of decorative elements applied to clean-lined and geometrical buildings that are otherwise bordering on International Style.
I have a strong feeling you could write a lot more about Mesoamerican borrowings by Mexican and Central and South American architects, which this book doesn't do so much as imagine, but I guess that's outside the scope.
