Ken Condon's Romanised recorded an impressive success in the Prix Jacques le Marois at Deauville.
A surprise winner of last year's Irish 2,000 Guineas, there were signs earlier this year he was coming back to something like his best when he was not beaten far in the Lockinge at Newbury and the Queen Anne at Royal Ascot.
Dropped in class last time out for the Minstrel Stakes, he received the perfect confidence boost in that Group Two at the Curragh to prepare him for this Group One assignment.
Settled beautifully for Billy Lee as Vocal Music and Condon's Success Days put the pace to the mile showpiece, Romanised always looked to be going best.
Coronation Stakes winner Watch Me was behind Romanised for most of the way, but failed to pick up as Lee drew alongside Shaman before quickening in style to win well.
Charlie Appleby's Line Of Duty flew late to grab third, narrowly behind Shaman.
