This mourning for Tammuz/Damuzi thing…Okay, let me run through some stuff.
There is a quote that comes from a tenth-century manuscript, Nabatean Agriculture, that contains much useful information. Somewhat controversially attributed to Ibn Wahshiyya, Nabatean Agriculture sounds like a fascinating text that mixed star lore and magic with extensive practical advice about agriculture; I wish there was a complete English translation available, but read about it here.
(As an aside, I’m also interested in the relationship between agriculture and star lore showing up independently in both Mesoamerica and the Middle East. There seems to be some good evidence for strengthening the thesis that ritual might have preceded agriculture and laid the groundwork for it, that the experience of time in ritual might have preceded the understanding of time necessary for agriculture. In the Americas, you have the mound complexes, and in the Old World, you have Gobekli Tepi.)
The quote in question describes how rites of lamentation were shared by devotees to both Tammuz (Dumuzi) and St. George at the time of the manuscript’s composition. I quote it here as an opportunity to consider the relationship between continuity and memory.
