Caput Mundi is a Latin phrase which literally means "Head of the world" whereas Roma Caput Mundi means "Rome capital of the world" and is one of the many nicknames given to the city of Rome throughout its history.
[1] The phrase is related to the enduring power of the city first as the capital of the Republic and the Empire, and later as the centre of the Catholic Church.
[6] It originates out of a classical European understanding of the known world: Europe, North Africa, and Southwest Asia.
The influence of Rome in the ancient world began to grow around the 2nd century BC as the Republic expanded across Southern Europe and North Africa.
The cultural influence of the local language of Rome (Latin) as well as Roman art, architecture, law, religion, and philosophy was significant.
