Cats… they hide everywhere and pop up when you do not expect them! For example, in this painting by Frans Floris in which a cat is visible only thanks to Reflectography, as it is not present in the final version.
And, did you know that a painting very similar to this one, now at the Palatine Gallery in Florence, can be seen in the “Cabinet d’amateur”, which represents the workshop of Jan Suellincks and is attributed to J. Franken II (now at the Musées Royaux des Beaux Arts in Brussels)? Can you spot it? Will there be a cat underneath there too?🐱
