Romanised gave trainer Ken Condon another magical Group 1 moment as last season's Irish 2,000 Guineas winner struck again at the highest level.
Billy Lee gave the four-year-old an exemplary ride, sitting behind the pace before kicking clear in the final stages. Favourite Watch Me failed to land a blow in behind.
Rupert Pritchard-Gordon, racing manager for winning owner Robert Ng, told Sky Sports Racing: "Ken and his team have done a great job. He knew he had the horse better than he had had him in a long time. You've got to ride him patiently and that's exactly what Billy did. It was impressive."
Condon added: "He came here last year and ran into an exceptional filly [Alpha Centauri]. We think after his Guineas win that he wasn't as good, but this year he's come back in good form and has kept improving.
"He was very professional and loves this ground. He has a lot of acceleration and gears and I'm delighted."
A return to France could be an option for Romanised as Condon said: "I think he could go for the Foret or the Breeders' Cup Mile."
Paddy Power introduced Romanised at 14-1 for the Breeders' Cup Mile.
