Tim's most astonishing discovery is the curved lower edge of the virginal, which in this documentary looks like hard evidence that Vermeer used a concave mirror.
So I pulled a few horizontal lines; the concave couldn't tell, but it's true that the sides of the piano are not horizontal.
There are almost no completely vertical sidelines, and the line at the front of the table and the ground are completely horizontal. Errors in reproductions are not excluded.
From now on, Vermeer has another angle...
