This looks like an interesting essay to write. I'd outline the essay based on your topic question. So
Introduction:
- brief history of both buildings
- statement of ur subtopics (" this essay will first_____" etc. )
Subtopic 1: design
- talk about who built the buildings
- their sizes are definitely different. You'll have to check that.
- siting- Parthenon on the acropolis, highest point. One in Greece, another in Rome. So one is a Greek temple the other roman. Difference is that Greek temples are dedicated to one god whereas roman temples are to many gods. This is bcos Romans believed that they were victorious in battle n conquering a place because they had the gods on their side. So the pantheon was built for the seven deities of the seven planets of ancient Rome. That's why the plan shows 7 niches, each intended for the seven gods of Rome.
- then u might also want to talk about the sculptures and reliefs of the parthenon.
- the columns on the Parthenon are massive.
- classical orders: parthenon uses the Doric order. It comes across as strong and masculine while pantheon uses the Corinthian order which is more ornate and more elegant. The Doric order also does not have a base.
- Parthenon is octastyle meaning it has eight columns on the front and peripteral meaning it has a single row of columns on all sides. The pantheon is also octastyle. Parthenon columns are designed to subtly slope inwards and the spacing btw the columns add to the effect of straight sturdy columns.
- pediment- sculpture on the Parthenon depicts the birth of Athena.
- in comparison, the interior of the pantheon is more spectacular. Before it was converted into a Christian church, the pediment used to house a bronze relief of Zeus.
- colour- it was discovered in the last decade that the Parthenon was once brightly colored.
Subtopic 2: lighting
-the orientation. The Parthenon was orientated to face the East so that the light from the rising sun would fall upon the statue of Athena. This would add to the 'godliness' of Athena as the people made their journey up to the temple in the morning for prayers.
- pantheon was a little diff cos it's not as open as the parthenon. Only light was through the oculus. I would think that the light falling on the statues at different times of day would have been awe-inspiring. I also remember my lecturer telling me that Hadrian used it as an audience hall n would stand where the light fell so he'd look godlike. The whole place also functioned as a sundial n a meeting place for votes.
Subtopic 3: shape
- the dome. The pantheon. It's a very cool dome. Amazing that the Romans could build such a structure without modern tech like reinforced concrete. Anyway, it has a span of 43 meters. Represents plato's philosophy about perfect forms- the cube, sphere, and equilateral triangle. Imagine the dome- sphere+cube+pyramid can all fit into that space.
The dome is also symbolic as the vault of heaven. The merging of the square base to the circular dome is symbolic of the connection between earth n heaven.
- coffers- important part of the dome structure. For weight distribution, structural integrity and to create the optical effect that the cella is taller and grander than it really is. If you see sections of the dome, it gets thinner nearer the top.
- it would also be good if you could compare plans of the 2 buildings. The parthenon plan is divided into the pronaos (open vestibule) then cella n then the epinaos( rear vestibule).
The pantheon is separated into the front portico then the circular cella. The portico consists of 16 corinthian columns. 8 in front the another two rows of four.
You'll probably need to rearrange some bits. But I hope my notes will help. Do u need to do referencing? I'd recommend borrowing general history books or more specific ones if you have to.
