Silhouettes of polished redware from the Ancient Egyptian (or, really, older than Ancient Egyptian) Naqada culture. That’s about 5,500 years old, a mere century or two before the very first written records anywhere.
Something about this presentation (from W. Petrie’s Corpus of Prehistoric Pottery and Palettes, published in 1921) really reminds me of 1970s wallpaper. The geometry of handmade shapes.
