The term "Roman-Egyptian" refers to the cultural and historical period when Egypt was part of the Roman Empire, beginning in 30 BCE after the defeat of Cleopatra VII and Mark Antony. This era saw a blend of Roman and Egyptian traditions, art, and religion, as the Romans integrated Egyptian customs into their own practices. During this time, cities like Alexandria flourished as centers of learning and commerce. The Romans adopted Egyptian deities, such as Isis, while also promoting their own gods. This fusion influenced architecture, with structures like the Temple of Dendur showcasing both styles.
