Answer 2

Origin of the Phrase "Перейти рубикон"

The phrase "Перейти рубикон" (pronounced "Pereyti rubikon") is a Russian idiom that translates to "to cross the Rubicon" in English. It is used to describe a decisive action or a point of no return. The phrase is derived from the historical event of Julius Caesar crossing the Rubicon River in 49 BC, which marked the beginning of the Roman Civil War.

The Rubicon River was the boundary between Gaul (modern-day France) and Italy. Roman law forbade any general from crossing the Rubicon River with an army, as it would be considered an act of treason against the Roman Senate. By crossing the river, Caesar defied the Senate's authority and initiated a civil war that ultimately led to his rise as the dictator of Rome.

The phrase "to cross the Rubicon" has since become a metaphor for taking a decisive and irreversible action. It is often used to describe situations where one is committing to a course of action with significant consequences, often with no turning back.
