The name Cyrus is derived from the Persian word "Kūrush", which means "far-sighted" or "young" in the ancient Persian language. It has its origins in the Persian Empire, which was founded in the 6th century BCE and spanned across parts of Western Asia and the Caucasus.

The name Cyrus gained significant historical prominence due to its association with Cyrus the Great, who ruled the Persian Empire from 559 BCE to 530 BCE. He was the founder of the Achaemenid Empire and is renowned for his military campaigns, as well as his policies of religious tolerance and respect for cultural diversity.

The name Cyrus is mentioned in several ancient texts, including the Hebrew Bible (Old Testament), where it refers to Cyrus the Great and his role in allowing the Jews to return to Jerusalem after their exile in Babylon. The biblical book of Ezra and the book of Isaiah both mention Cyrus by name.

The earliest recorded examples of the name Cyrus can be traced back to the 6th century BCE, during the reign of Cyrus the Great. Throughout history, several notable individuals have borne this name, including:

1. Cyrus the Younger (423 BCE - 401 BCE), a Persian prince and younger son of Darius II, who led a rebellion against his brother Artaxerxes II.
2. Cyrus of Panopolis (5th century CE), a Greek poet and philosopher from Egypt.
