Orb of Isis

The Orb of Isis is an ancient Egyptian relic that was featured in the "Treasures of Isis" exhibit at the Springsonian Museum.

History
When Homer and Lisa broke into the museum at night, they accidently discovered that the orb was actually a music box. As they bonded over their discovery, Lisa remarked that they are the first people to hear the orb's melody in thousands of years.

While they are inside the torture chamber, Milhouse and Lisa walk past the orb.
