Godolphin, which had been without a Group 1 victory in Europe all season, scored two within minutes of each other in France and Germany on Sunday.
Librettist and Frankie Dettori got things started with a gutsy victory in the Prix du Haras le Fresnay-Le-Buffard Jacques Le Marois (Fr-I) at Deauville.
Dettori pushed the son of Danzig to the lead with just over a furlong left to run, and the colt stayed on strongly to win by a neck over Manduro. The Sir Michael Stoute-trained filly Peeress was just a head further back in third.
Favored Stormy River appeared to be making a move about two furlongs out, but flattened out on the soft turf and finished fourth. Ad Valorem and Jamie Spencer were never in the hunt and finished fifth.
Librettist has now won six of seven career starts. He is out of the Alleged mare Mysterial, and is a half brother to Group 1 winner Dubai Destination. He was bred in Kentucky by Calumet Farm.Cherry Mixes it Up in Germany
Moments after stablemate Librettist landed Group 1 glory, Cherry Mix joined in the fun and won the Rheinland-Pokal der Sparkasse KolnBonn (Ger-I) impressively at Cologne.
The 5-year-old son of Linamix romped home by four lengths over Fracas, with Collier Hill third.
Cherry Mix was ridden by Kerrin McAvoy. Connections stated that the Grosser Preis von Baden (Ger-I) on September 3 might be the horse's next start.
