One of the things I was most excited to see in Heraklion was the Phaistos Disc. This clay disc was discovered in Crete in 1908 and is covered in symbols from an unknown language. No one knows what it means. I learned about the disc a few years back when I was researching “mysteries” to knit into a scarf. (I ended up going with the Wow Signal.) Isn’t it cool? Now we have a smaller magnetic version stuck on our fridge.
