Sure did.
Bravo, 9 points on the Pun-o-Meter.
ChiMagnet-- Sounds like the kind of urban myth that gets put out in a certain type of art book; you know, Bosch was a heretical alchemist, Da Vinci was a hermaphrodite, and all that. Sells well.
Now, if that paint mixture was common practice, why only Goya, and not also Josh Reynolds and Hogarth and David Caspar Friedrich and Mengs and David and Ingres all those other majority of artists who were imminently sane in that period? A statistical sampling of one isn’t a good argument for a trend.
Also, lead poisoning has many other symptoms besides neurological problems. If it was widespread among painters, one would expect them to be characterized as a sickly bunch in general, not just crazy. (And like others have said, I am having trouble coming up with a list of more than a few painters that could have been charactized as having severe mental problems.)
From here
If lead poisoning was common among painters, you would expect to hear of other neurological problems like inability to hold a brush, or to walk, at least as much as insanity.
