In Homer’s “Odyssey,” the notorious Trojan horse was a formidable gift from the Greeks. Later, the Roman poet Virgil (70-19 BC) wrote in the Aeneid (II, 49), “Timeo Danaos et dona ferenteso,” which, in English, reads “Beware of Greeks bearing gifts.”
A Greek gift, which in today’s world would mean from one’s adversary, refers to giving something away with the intention of causing harm to the recipient.
