Ceistiu, dam of this season's exciting Royal Ascot and Goodwood winner Merchant, will be offered at the Goffs November Breeding Stock Sale, which takes place Nov. 21-22.
A daughter of Vocalised, Ceistiu is in foal to Mehmas and is a sister to multiple group 3 winner and group 1-placed Steip Amach and a half sister to the group-winning Ceisteach, while another half sister produced last year's Vincent O'Brien National Stakes (G1) winner Scorthy Champ.
Merchant, last seen winning the Gordon Stakes (G3) at Goodwood, had also struck at Royal Ascot when defeating subsequent Irish Derby (G1) runner-up Serious Contender in the King George V Stakes. He looks set to become a leading middle-distance performer next term.
Ceistiu will be consigned by Clare Manning's Boherguy Stud on behalf of breeder Jim Bolger.
He said: "We're looking forward to offering a most attractive young mare—already the dam of a highly exciting group winner in Merchant and from a very happening pedigree. She is also in foal to an exceptional stallion, Mehmas."
Goffs group chief executive Henry Beeby said: "Merchant looks an extremely exciting prospect for the future after his Ascot and Goodwood victories, and the chance to buy his dam, in foal to the brilliant Mehmas, is hugely appealing.
"We are grateful to Mr. Bolger for once again entrusting Goffs with a mare of this caliber, which follows a number of successful collaborations over the years, not least with the likes of Banimpire, who topped Goffs November at €2.3 million."
He added: "The Goffs November Sale has long been a leading source of group 1 producers, and this year's catalog, featuring Ceistiu alongside outstanding drafts from HH Aga Khan Studs, Godolphin, Moyglare and so many more, is shaping up to be another unmissable event for international buyers."
