Several historians have suggested that reports of Gabrielle's extravagance have been greatly exaggerated, and they point out that, during her 14-year residency at Versailles she spent as much as Louis XV's mistress, Madame de Pompadour, had spent in one. Others have contended that to some extent she deserved her negative reputation because, despite the inaccuracies of the claims that she was sexually disreputable, other criticisms of her were valid: she was cold, self-centred, self-indulgent, and masked a love of gossip and intrigue behind a sweet-toned voice and flawless manners. This argument was particularly championed by the author and biographer Stefan Zweig, who wrote: "Not even Madame de Maintenon, not even the Pompadour, cost as much as this favourite, this angel, with downcast eyes, this modest and gentle Polignac. Those who were not themselves swept into the whirlpool, stood at the marge contemplating it with astonishment ... the Queen's hand was invisibly guided by the violet-eyed, the lovely, the gentle Polignac."
