It was prince Thutmose IV who made the sphinx famous again in Egypt way after it was built. As the story was told the sphinx was buried and Prince Thutmose IV happened to fall asleep next to it. He had a dream that Horus told him to renew it. Now I know what your thinking, pretty freaky right! Well it was thought he used this to receive popularity from the people to take the throne. Eventually he did but his reign was short because his dad didn't die soon enough for him. He also didn't receive a big tomb rather a smaller tomb than he intended. Even though he didn't have much of a term as a Pharaoh, he managed to slide into a part of the Sphinx history.
This is the Sphinx at night. Now imagine a grown man sleeping next to this thing.
