What is timeo danaos et dona ferentes?

"Timeo Danaos et dona ferentes" is a Latin phrase that translates to "I fear the Greeks, even when they bear gifts" in English. It is a famous line from the Roman poet Virgil's epic poem, the Aeneid.

The phrase comes from the story of the Trojan Horse, where the Greeks used cunning deception to infiltrate the city of Troy. The Trojans, despite having suspicions, ultimately fell for the trick and brought the horse into their city walls as a peace offering. This led to the fall of Troy and the destruction of the city.

The phrase has since become an expression warning against accepting gifts from an enemy or being overly trusting of others, as they may have ulterior motives. It is often used to caution against naivety and to remind people to be vigilant and wary of potential deception.
