This is a comparison of the portrait of a woman found in Sirrus' chamber on Mechanical Age in Myst with the portrait of Madame In's Moitessier assise, painted in 1856 by Jean Auguste Dominique Ingres.

You can find a larger image of this portrait here on The Art on Canvas web site.

Thanks to Peter Hargreaves for finding this and sharing it with the Lysts! I've recently learned that Myro made an independent discovery of the same information.

Myst, Riven, and all things D'ni are the creation of Cyan Worlds, Inc.
