Final answer:
The line 'I fear Greeks, even bearing gifts' is from Virgil's Aeneid, spoken by Laocoon about the Trojan Horse.
Step-by-step explanation:
The famous line 'I fear Greeks, even bearing gifts' is attributed to Laocoon in Virgil's epic poem, the Aeneid.
This line is famously associated with the story of the Trojan Horse, where the Greeks offered a giant wooden horse as a deceptive gift to the Trojans amidst the Trojan War, which actually concealed Greek soldiers inside.
It reflects the timeless wisdom that one should be wary of enemies bearing gifts, as it could be a ploy or trick.
