Beware of Greeks bearing bearings
A little known fact about Epsuis, chief engineer of the Trojan Horse, is that back home in Thrace he ran a fabulous ball bearing business. Laocoon, the uncle of the Trojan prince Aeneas, warned to "beware of Greeks bearing gifts", according to the poet Virgil. What the poet neglected to mention was that a Greek with ball bearings is more dangerous than most gifts. Evidence the Ball Bearing Genocide of 1798 in Pakistan.
