The Mexica (Aztecs) used a solar calendar made up of eighteen months, with each month dedicated to a specific god in their pantheon and celebrated with a different set of rituals. Panquetzaliztli, the fifteenth month, dedicated to the national god Huitzilopochtli (Hummingbird on the Left), was significant for its proximity to the winter solstice, and for the fact that it marked the beginning of the season of warfare. In The Fifteenth Month, John F. Schwaller offers a detailed look at how the celebrations of Panquetzaliztli changed over time and what these changes reveal about the history of the Aztecs. Drawing on a variety of sources, Schwaller deduces that prior to the rise of the Mexica in 1427, an earlier version of the month was dedicated to the god Tezcatlipoca (Smoking Mirror), a war and trickster god. The Mexica shifted the dedication to their god, developed a series of ceremonies—including long-distance running and human sacrifice—that would associate him with the sun, and changed the emphasis of the celebration from warfare alone to a combination of trade and warfare, since merchants played a significant role in Mexica statecraft. Further investigation shows how the resulting festival commemorated several important moments in Mexica history, how it came to include ceremonies associated with the winter solstice, and how it reflected a calendar reform implemented shortly before the arrival of the Spanish. Focused on one of the most important months in the Mexica year, Schwaller’s work marks a new methodology in which traditional sources for Mexica culture, rather than being interrogated for their specific content, are read for their insights into the historical development of the people. Just as Christmas re-creates the historic act of the birth of Jesus for Christians, so, The Fifteenth Month suggests, Panquetzaliztli was a symbolic re-creation of events from Mexica myths and history.

The book focusses on the origin and transformation of the priestly festival calendar. Since the epoch-making work of Julius Wellhausen at the end of the 19th century the differences between the various ancient Israelite festival calendars have often been explained in terms of a gradual evolution, which shows an increasing historicisation, denaturalisation and ritualisation. The festivals were in Wellhausen's view gradually detached from agricultural conditions and celebrated more and more at fixed points in the year. This study tries to show that the changes in the priestly festival calendar reflect a conscious effort to adapt the ancient Israelite festival calendar to the semi-annual layout of the Babylonian festival year. The ramifications of the change only come to the fore after a careful study of the agricultural conditions of ancient Israel - and Mesopotamia - makes clear that passover and the festival of unleavened bread were originally celebrated in the second month of the year. The first month of the year envisaged by the priestly festival calendar for the celebration of passover and the festival of unleavened bread in turn mirrors the date of one of the two semi-annual Babylonian New Year festivals. The two Babylonian New Year festivals were celebrated exactly six months apart at the vernal and autumnal equinoxes. In order to adapt the ancient Israelite festival calendar to the Babylonian scheme with two New Year festivals a year, the date of passover and the festival of unleavened bread had to be moved up by one month. The consequences for the origin of passover, the festival of unleavened bread, the festival of weeks and the festival of huts are charted and the relations between the various ancient Israelite festival calendars are determined anew.
