Final answer:
Hadrian rebuilt the Parthenon in Rome after it was destroyed by fire.
Step-by-step explanation:
The emperor who rebuilt the Parthenon in Rome after an earlier structure was destroyed by fire was Hadrian. The original Parthenon in Rome was built by Agrippa and was damaged by fire around 80 CE. Hadrian, who succeeded Trajan as emperor, conceived and possibly even designed the new building, which was much larger and more impressive than the original. Hadrian installed a false inscription attributing the new building to Agrippa as an act of pious humility.
The Pantheon in Rome was rebuilt by Emperor Hadrian around 125 CE following a fire. The Parthenon in Athens, which is a separate structure, was rebuilt in the fifth century BCE during the Periclean Revival after being damaged in the Persian War.
The emperor who rebuilt the Pantheon in Rome after it was damaged by fire in 110 CE was Emperor Trajan, who initiated its reconstruction. However, it was his successor, Hadrian, who is credited with the eventual creation of the new, more impressive building that stands today. While the Pantheon is often confused with Greece's Parthenon, the latter is an entirely separate and distinct structure located on the Acropolis in Athens. The Pantheon that stands in Rome and is often praised for its architectural wonder was completed under Emperor Hadrian around 125 CE. Hadrian's design broke away from the original, more conventional rectangular temple built by Agrippa, and he even included an inscription attributing the building to Agrippa as an act of reverence.
The Parthenon, on the other hand, was rebuilt after its destruction in the Persian War as part of the Periclean Revival in the fifth century BCE. Situated in Athens, it was dedicated to the goddess Athena and constructed under the leadership of the Athenian statesman Pericles, employing the architectural expertise of Iktinos and Kallikrates, along with the artistic direction of Phidias.
