Final answer:
The Colosseum, Diocletian's Palace, and the Doges Palace are examples of art/architecture used to legitimize rule.
Step-by-step explanation:
An example of a piece of art/architecture that was used to legitimize rule is the Colosseum in Rome. Built in the 1st century CE, the Colosseum was a grand amphitheater that symbolized the power and authority of the Roman Empire. It was used for public spectacles and entertainment, including gladiator fights and mock naval battles, which served to highlight the might and control of the Roman rulers.
Another example is Diocletian's Palace in Split, Croatia. This palace, built in the 4th century CE, was designed as a secure retirement home for the Roman emperor Diocletian. Its grand architecture and use of columns, peristyles, and entablatures created monumental spaces that emphasized Diocletian's imperial power and legitimacy.
In addition, the Doges Palace in Venice, Italy, served to legitimize the rule of the political aristocracy of the Republic of Venice. Its intricate architectural details, such as rhythmic levels of columns and pointed arches, reflected the wealth and power of the ruling class, reinforcing their authority.
