Just days after a bikini photo of the pregnant Duchess published in Chi magazine upset the Palace, Kate Middleton was attacked by a British writer who called her a “shop-window mannequin with no personality," compared to her deceased mother-in-law Princess Diana.

Hilary Mantel, an award-winning novelist, went on the rant during a lecture at the British Museum in London earlier in February, when asked what book she would give to a famous person of her choice. Mantel chose Middleton, and then compared her to Princess Diana, saying she sees the Duchess as a "jointed doll on which certain rags are hung.”

"Kate seems to have been selected for her role of princess because she was irreproachable: as painfully thin as anyone could wish, without quirks, without oddities, without the risk of the emergence of character,” Mantel said. "She appears precision-made, machine-made, so different from Diana whose human awkwardness and emotional incontinence showed in her every gesture.

"In those days (Kate) was a shop-window mannequin, with no personality of her own, entirely defined by what she wore,” she added. "These days she is a mother-to-be, and draped in another set of threadbare attributions.”

Mantel also discussed how Middleton is perceived by the media, saying that “once she gets over being sick, the press will find that she is radiant. They will find that this young woman's life until now was nothing, her only point and purpose being to give birth."

Middleton wasn’t the only victim of Mantel’s rant; The author also blasted Paul Emsley, who painted the first official portrait of the Duchess. She said her eyes appear “dead” in the portrait, just above "the strained smile of a woman who really wants to tell the painter to bugger off.”

British media have lambasted Mantel for the scathing words, including the Daily Mail, which called it “an astonishing and venomous attack on the Duchess of Cambridge.”

Below is a text excerpt of Mantel’s lecture, courtesy of the London Review of Books, where the author talks about Marie Antoinette, Kate Middleton and the future of the monarch.

“Last summer at the festival in Hay-on-Wye, I was asked to name a famous person and choose a book to give them. I hate the leaden repetitiveness of these little quizzes: who would be the guests at your ideal dinner party, what book has changed your life, which fictional character do you most resemble? I had to come up with an answer, however, so I chose Kate, the Duchess of Cambridge, and I chose to give her a book published in 2006, by the cultural historian Caroline Weber; it’s called Queen of Fashion: What Marie Antoinette Wore to the Revolution. It’s not that I think we’re heading for a revolution. It’s rather that I saw Kate becoming a jointed doll on which certain rags are hung. In those days she was a shop-window mannequin, with no personality of her own, entirely defined by what she wore. “These days she is a mother-to-be, and draped in another set of threadbare attributions. Once she gets over being sick, the press will find that she is radiant. They will find that this young woman’s life until now was nothing, her only point and purpose being to give birth.

“Marie Antoinette was a woman eaten alive by her frocks. She was transfixed by appearances, stigmatised by her fashion choices. Politics were made personal in her. Her greed for self-gratification, her half-educated dabbling in public affairs, were adduced as a reason the French were bankrupt and miserable. It was ridiculous, of course. She was one individual with limited power and influence, who focused the rays of misogyny. She was a woman who couldn’t win. If she wore fine fabrics she was said to be extravagant. If she wore simple fabrics, she was accused of plotting to ruin the Lyon silk trade. But in truth she was all body and no soul: no soul, no sense, no sensitivity. She was so wedded to her appearance that when the royal family, in disguise, made its desperate escape from Paris, dashing for the border, she not only had several trunk loads of new clothes sent on in advance, but took her hairdresser along on the trip. Despite the weight of her mountainous hairdos, she didn’t feel her head wobbling on her shoulders. When she returned from that trip, to the prison Paris would become for her, it was said that her hair had turned grey overnight.

“Antoinette as a royal consort was a gliding, smiling disaster, much like Diana in another time and another country. But Kate Middleton, as she was, appeared to have been designed by a committee and built by craftsmen, with a perfect plastic smile and the spindles of her limbs hand-turned and gloss-varnished. When it was announced that Diana was to join the royal family, the Duke of Edinburgh is said to have given her his approval because she would ‘breed in some height’. Presumably Kate was designed to breed in some manners. She looks like a nicely brought up young lady, with ‘please’ and ‘thank you’ part of her vocabulary. But in her first official portrait by Paul Emsley, unveiled in January, her eyes are dead and she wears the strained smile of a woman who really wants to tell the painter to bugger off. One critic said perceptively that she appeared ‘weary of being looked at’. Another that the portrait might pass muster as the cover of a Catherine Cookson novel: an opinion I find thought-provoking, as Cookson’s simple tales of poor women extricating themselves from adverse circumstances were for twenty years, according to the Public Lending Right statistics, the nation’s favourite reading. Sue Townsend said of Diana that she was ‘a fatal non-reader’. She didn’t know the end of her own story. She enjoyed only the romances of Barbara Cartland. I’m far too snobbish to have read one, but I assume they are stories in which a wedding takes place and they all live happily ever after. Diana didn’t see the possible twists in the narrative. What does Kate read? It’s a question.

“Kate seems to have been selected for her role of princess because she was irreproachable: as painfully thin as anyone could wish, without quirks, without oddities, without the risk of the emergence of character. She appears precision-made, machine-made, so different from Diana whose human awkwardness and emotional incontinence showed in her every gesture. Diana was capable of transforming herself from galumphing schoolgirl to ice queen, from wraith to Amazon. Kate seems capable of going from perfect bride to perfect mother, with no messy deviation. When her pregnancy became public she had been visiting her old school, and had picked up a hockey stick and run a few paces for the camera. BBC News devoted a discussion to whether a pregnant woman could safely put on a turn of speed while wearing high heels. It is sad to think that intelligent people could devote themselves to this topic with earnest furrowings of the brow, but that’s what discourse about royals comes to: a compulsion to comment, a discourse empty of content, mouthed rather than spoken. And in the same way one is compelled to look at them: to ask what they are made of, and is their substance the same as ours.

“I used to think that the interesting issue was whether we should have a monarchy or not. But now I think that question is rather like, should we have pandas or not? Our current royal family doesn’t have the difficulties in breeding that pandas do, but pandas and royal persons alike are expensive to conserve and ill-adapted to any modern environment. But aren’t they interesting? Aren’t they nice to look at? Some people find them endearing; some pity them for their precarious situation; everybody stares at them, and however airy the enclosure they inhabit, it’s still a cage.”
