That's Rusty
Paolo Veronese depicts "Four Allegories of Love" which are on permanent display inside the National Gallery : here is 'Happy Union' that I happen to like because it looks a lot like Rusty in the lower right corner of the portrait. The other three (and far more interesting , really) are 'Unfaithfulness', 'Scorn', and 'Respect'. Veronese painted the set in 1575 for a private patron's interior walls (NB I got a dressing down for my photo since No Photos Allowed at the museum. I chat with a friendly guardsman about this as I do not use a flash nor harm the painting. He notes the rule for "security purposes" but agrees there may be a "commercial reason" as well so I buy a few post cards).
