Annick Lautraite states that there are only four undisputed surviving works originally painted by Raphael on canvas^{289 :}

She omits La Donna Velata which the Pitti describes as painted on canvas (dipinto su tela)²⁹⁰, and Putscher, who examined the painting out of the frame writes of Originalleinwand (original canvas)²⁹¹. Both Camesasca²⁹² and de Vecchi²⁹³ state that it is on panel; yet other examples of misleading mistakes in standard reference books.

Sylvie Béguin²⁹⁴ cites Shearman and Emile-Mâle, who observe that the canvas of Baldassare Castiglione is unusually fine. Annick Lautraite gives a thread-count of the Louvre’s two canvases (Castiglione and the Double Portrait) which

“…on average, is 16 vertical and 19 horizontal to the square centimetre.”²⁹⁵

The thread-count of the Tondo is on average 22 vertical and 25 horizontal to the square centimetre. This again is an exceptionally fine-woven canvas.

The canvas for the Sistine Madonna was described by Schlesinger in 1823 as

“fine, put together from three bits, yet quite strong and sound.”²⁹⁶
