The daughter of St Mark’s Basilica is a half-sister to Magic Wand and Chicquita and made a winning debut at the Curragh when beating better-fancied stablemate Minerva.
O’Brien has also entered Beautify, the only horse to beat Nunthorpe-bound Lady Iman this season, and Precise.
Sir Mark Prescott’s Moon Target, the Owen Burrows-trained Touleen and George Boughey’s Awaken, second to Venetian Sun in the Albany, are other top-class prospects entered.
As is David Menuisier’s Inis Mor, who created a favourable impression when winning on her debut at Newmarket, although she does have another option.
“She’s entered at Newmarket on Friday as well as the Prestige. We need to decide whether to run her with a penalty or in the Group Three,” said Menuisier.
“It wasn’t really a surprise how well she won, she had been working well in the morning. I don’t know about the strength of the race, but she’d always worked well.
“She can only improve when she goes up in trip when you see her pedigree.
“The aim is to run her in the Arqana race, the Criterium d’Automne, on the day before the Arc.”
