“From the 18th century, and perhaps even earlier, hollow eggs on which sacred texts had been written in micrography were used to decorate European sukkahs. Not all the texts related directly to the holiday of Sukkot, the Festival of Booths: this example has Song of Songs 1-4:7 inscribed in miniscule letters. At times feathers were added to the hanging egg, so that it looked like a bird in flight.”
