One day, Gylius was walking around the Hagia Sophia and managed to enter the Basilica Cistern with a torch through the stone steps of it. He saw a wooden backyard building in front of a very large underground cistern. He told that the people were pulling the water from the large round holes from their ground floor of the houses and even fished there. During his expedition, Gyllius identified each column of the cistern and published them on his travel book. Gyllius influenced many other travelers with his time in Istanbul.
