The temple was erected on the remains of the
Domus Transitoria and
Domus Aurea, two mansions commissioned by the disgraced Emperor
Nero. Buried intact beneath the temple is an elaborate domed
rotunda from the Domus Transitoria, with marble-lined pools and paving in multicoloured
opus sectile. Unimpressed by
Hadrian's architectural design for the temple, his most brilliant architect,
Apollodorus, made a scornful remark on the size of the seated statues within the cellae, saying that they would surely hurt their heads if they tried to stand up from their thrones. Apollodorus was banished and executed not long after this. According to the ancient historian
Ammianus Marcellinus, the temple was among the great buildings of Rome which astonished the Emperor
Constantius II on his visit to the city in 357. The sanctuary was closed during the
persecution of pagans in the late Roman Empire. Restoration was performed under the short-lived
usurper Eugenius (392–394), a Christian sympathetic to pagan worship. However, as with many of Rome's majestic ancient buildings, the temple was later targeted for its rich materials. In 630, with the consent of the Emperor
Heraclius,
Pope Honorius I removed the gilt-bronze tiles from the roof of the temple for the adornment of
St. Peter's. A severe earthquake at the beginning of the 9th century is believed to have destroyed the temple. Around 850
Pope Leo IV ordered the building of a new church,
Santa Maria Nova, on the ruins of the temple. After a major rebuilding in 1612, this church was renamed Santa Francesca Romana, incorporating Roma's cella as the
belltower. A
veduta engraving by
Giovanni Battista Mercati depicts the site in 1629. The vast quantity of marble that once adorned the temple has all but disappeared due to its use as a raw material for building projects from the Middle Ages onwards. The Italian archaeologist Rodolfo Amedeo Lanciani makes reference to his discovery of a lime kiln in close proximity to the temple in his work
The Destruction of Ancient Rome. ==Architecture==
