Places such as Poverty Point, Mound City, and Chaco Canyon remind us that the siting of ritual infrastructure in ancient North America was a matter of cosmological precedent. The cosmic gravity of these places gathered persons periodically in numbers that challenged routine production. Ritual economies intensified, but beyond the material demands of hosting people, the siting of these places and the timing of gatherings were cosmic work that preconfigured these outcomes. A first millennium AD civic-ceremonial center on the northern Gulf Coast of Florida illustrates the rationale for holding feasts on the end of a parabolic dune that it shared with an existing mortuary facility. Archaeofauna from large pits at Shell Mound support the inference that feasts were timed to summer solstices. Gatherings were large, judging from the infrastructure in support of feasts and efforts to intensify production through oyster mariculture and the construction of a large tidal fish trap. The 250-year history of summer solstice feasts at Shell Mound reinforces the premise that ritual economies were not simply the amplification of routine production. It also suggests that the ecological potential for intensification was secondary to the cosmic significance of solstice-oriented dunes and their connection to mortuary and world-renewal ceremonialism.

宇宙同步性的海洋仪式经济：佛罗里达州北部墨西哥湾沿岸市民礼仪中心的夏至活动

Poverty Point、Mound City 和 Chaco Canyon 等地方提醒我们，古代北美的仪式基础设施选址是宇宙学先例。这些地方的宇宙引力周期性地聚集了大量挑战常规生产的人。仪式经济得到加强，但除了接待人们的物质需求之外，这些地方的选址和聚会的时间是预先配置这些结果的宇宙工作。佛罗里达州北部墨西哥湾沿岸的第一个公元一千年公民礼仪中心说明了在抛物线沙丘的尽头举行盛宴的理由，该沙丘与现有的太平间设施共享。来自贝壳丘大坑的古动物群支持了盛宴时间为夏至的推论。聚会规模大，从支持节日的基础设施来看，通过牡蛎海水养殖和大型潮汐捕捞器的建设努力集约化生产。Shell Mound 250 年的夏至盛宴历史强化了这样一个前提，即仪式经济不仅仅是常规生产的放大。它还表明，集约化的生态潜力次于以至日为导向的沙丘的宇宙意义及其与太平间和世界更新仪式的联系。
