This is why I love gravity falls. Any sleep deprived AP art student would recognize the ancient scripts of bill cipher’s incantations as an allusion to the Running Horned Woman (tassili n'ajjer), and among other works as well. Just look at those dots implying a glow effect around bill cipher, that’s totally a motif of the horned woman. I don’t know if Alex Hirsch is the genius behind that single drawing in that scene but somebody obviously did their homework and it made me super happy. This series has so many amazing Easter eggs. I could make a whole blog dedicated to the subtle references in pop culture throughout the whole series.
