Hmm, indeed. Hadn't noticed that. Extremely ridiculous how downplayed it is in the game.

And yes, 1812 was the year the painting was made. However, coincidentally, the other two paintings from that particular Glyph (the painting of Washington and Lafayette from 1781 and the one of Queen Elizabeth I from 1559) seem to have been painted in the year they obtained their Apples of Eden.
