‘Days and months are itinerants on an eternal journey; the years that pass by are also travellers’. – Matuso Bashō (1644-94)
I noted this quotation a few years ago; a dozen in fact. Reading it last night triggered thoughts that spawned a few more. I wish you good luck on this eternal journey.
It’s amazing to me that so many people on different continents came to live in caves carved from volcanic tuff. The Puebloans or Anasazi in New Mexico, Etruscans in Italy, and the Cappadocians in Turkey spring to mind. Each realised, independently, that tuff was relatively easy to carve into negative moulds for habitation. Conversely, the Rapa Nui on Easter Islander chose to cut positive shapes from similar material.Presumably their moai have religious purpose. While time may travel, coeval independent solutions seem to occur quite frequently.
