Hi everyone!
We are exploring the Ancient Roman Art and in the last post we started with the foundations of Rome, literally… 😀
Today we are going to talk more about Roman architecture, but in a more “traditional” way. We are going to learn more about the most important temple in Ancient Rome: Temple of Jupiter Optimus Maximus.
The temple, also known as the Temple of Jupiter Capitolinus gave the name to the hill where it has been built over: Capitoline Hill.
The Capitoline Hill
This hill is one of the seven on which Rome was built and one of the most important. The name’s origin is interesting and related to a legend. Ancient sources connect the name to the Latin word “caput” (“head”, “summit”) because when laying the foundations for the temple, the head of a warrior was found: “Tolus” or “Olus“. The combination of the two words made the adjective “Capitolium” with the meaning of “indestructible” (“eternal”).
The Temple
Traditionally the Temple was dedicated, according to Livy, on September 13th, 509 BC (the founding year of the Roman Republic). It was the oldest large temple in Rome, and, like many temples in central Italy, shared features with Etruscan architecture. But in 83 BC it was destroyed by a fire, and a replacement in Greek style was completed in 69 BC. After that other 2 fires happened and the Temple was rebuilt again each time. So not the luckiest temple…
Because of that, the Temple changed size and style many times and what we have today is just some ruins of the podium and foundations. But, thanks to some old sources and findings, scholars were able to build a model of the first version. It seemed to be much larger than other Roman temples for centuries after, not far short of the largest Greek temples with a plan of 60 m × 60 m (200 ft × 200 ft).
QUIZ
Can you see the most famous decoration in the interactive image? An hint: check the acroterion
Cella… or more?
Inside there were 3 separate celle. We learned from the post on the Greek temples that cella was usually containing a cult image or statue representing the particular deity venerated in the temple. So how is it possible to have 3 of them?? The reason is that even if the “main” god was Jupiter, the Temple was actually dedicated to the “Capitoline Triad“: a group of three deities who were worshipped in ancient Roman religion. So not only Jupiter, the king of the gods, but also Juno (his wife and sister…yes you heard correctly…but they are gods and they used to do weird stuff) and Jupiter’s daughter Minerva (the goddess of wisdom).
The temple was so beautiful and appreciated for the style that it established a new model for sacred architecture. In particular the terracotta decorations inspired many temples in Italy up to the 2nd century BC. Of course a lot changed after the fires and today not a lot survived, however, the temple is considered one of the most important Ancient Roman architectures in history. And we are going to discover more soon, so stay curious! Ancient Roman Art: Temple of Jupiter Optimus Maximus Ancient Roman Art: Temple of Jupiter Optimus Maximus
Among the many terracotta decorations, the most famous was for sure the one with Jupiter driving a quadriga located on top of the roof as an acroterion.
You found the answer! Good job 🙂
The temple was highly decorated on the style of the Etruscan Temples. The decorations were made of terracotta and painted with vibrant colors
Recontructions usually show wide eaves and a collonade stretching down the sides and with three rows of colomns on the front side. While none on the back
The doors represent the entrance to the celle where the statues and (probably) the offers/treasure were kept.
The unusal fact is the presence of 3 doors since the Temple was not dedicated jus to Jupiter, but also to Juno and Minerva. The so called "Capitoline Triad"
The podium was tall and highly decorated as well. A section of it with the foundations are the only parts that survived
