Angels & Demons
Using the poem he finds in Galileo’s Diagramma, Langdon tries to find the first Altar of Science, the first stop on the Path of Illumination, where the first Cardinal is due to be killed at 8pm. He thinks it is the Pantheon, due to the first line of the poem:“From Santi’s earthly tomb with demon’s hole”.The Pantheon is oldest surviving Roman temple, built originally in 27 BC by Marcus Agrippa, whose name it still bears. It is named for all the Roman state gods, pan meaning all and theos meaning Gods in Greek. Most temples at the time were dedicated to one or two deities. The first Pantheon was a square building as built by Agripps and burned down in the fire of AD 80.It was rebuilt in AD 125 by the Emperor Hadrian and this is the building you see today.
