How was Roman religion similar to Greek mythology? What was the most famous Roman temple?

Hint: The Roman religion consists of the worship of a large group of Greek or Roman gods such as Juno, Mars, Jupiter and Minerva. Due to the presence of Greek colonies Romans adopted many of the Greek gods as their own. This resulted in religion and myth became one entity.

Complete answer: Ancient Greeks and Romans existed in the middle ages. There are a lot of similarities between the Roman gods and Greeks because the Roman religion was based on Greek religion. The Greek mythology was founded about a millennium before the Roman and Romans founded their religion on the basis of Greek religion. Under the influence of Greek colonies Roman gods became more of a human characteristic of love, hate and jealousy etc. So, Greek and Romans shared commonalities in their religion such as the polytheistic religion which is a belief or a worship of multiple gods or devinities. Both cultures had more than 30 gods. Furthermore the only difference between the two was in the names of their gods as both cultures had God of war, Goddesses of wisdom, God of sea etc. in Greek mythology the King of gods is referred to as Zeus whereas Romans called their King of gods as Jupiter. Greeks queen of gods is Hira whereas Romans queen of gods is Juno.
Thus even do Roman religion was similar to Greek mythology but they had changed the religion and beliefs according to their own culture. Even though the Empire expanded across the Balkans, Asia Minor and Egypt and Roman religion observed many of the gods and culture of these different regions but the primary influence would always remain of Greece.

Note: It was under the rule of emperor Constantine that Christianity flourished in Rome and even after his death Christianity continued to grow and overshadow and replace the traditional Roman religion and made Rome a new centre of Christianity. Despite the changes in society starting from Roman religion and Greek mythology to the emergence of Christianity, religion remained an important part of Roman society.
