Consulting a Figurative System of Human Knowledge and Building a Pillow Fort

Seven sleepers (Menologion of Basil II)

French scientist and contributor to Encyclopédie ou Dictionnaire raisonné des sciences, des arts et des métiers, Louis-Guillaume Le Monnier was born on June 27, 1717.

I love encyclopedias. We had a white and green leather set, published circa 1962 (I only know that because of the number of times they made it into the citations of a great many poorly-researched high school papers in the early-to-mid 1990s and that according to these volumes, the moon landing had not happened yet). I am positive encyclopedia diagrams lead directly to my interest in mixed media art. I recall in particular the “F” volume had an intricate series of layered pictures of the anatomy of a frog, using clear sheets and onion skin paper that was just lovely.

Also born on June 27th: musician Elmo Hope, Helen Keller, and physicist and astronaut Joseph P. Allen.

June 27th is also Seven Sleepers Day. Known as Siebenschläfertag, it’s basically German groundhog’s day. Folklore says that today’s weather predicts what the weather will be like in July and August. Though this is a German holiday, the medieval story of the Cave of the Seven Sleepers is found in both Christian and Islamic religious traditions.

You can take a day trip to the Cave of the Seven Sleepers in the Dead Sea for less than $60, excluding travel costs to Amman, the capital city of Jordan. I am going to go out on a limb and guess that, like me, you could not in your wildest dreams afford this right now so how about you build a pillow fort and nap inside it instead? It will feel hot and stuffy, and presumably also predict the weather for the next 8-12 weeks.
