Luca Giordano, 1634-1705, Perseus turning Phineas and his Followers to Stone early 1680s © The National Gallery, London
Andromeda was betrothed to Phineas, until Perseus rescued her from a sea monster and it was agreed she would marry him instead. At the wedding celebrations Phineas and his followers burst in to attack Perseus, who unveiled the severed head of the gorgon, Medusa, and turned them to stone. This scene of high drama, recalling more tranquil feasts represented in 16th-century Venetian painting, is focused on the figure of Perseus in rich blue and his furious assailants, led by Phineas, who wears a helmet in the far left of the painting, turning the colour of stone as they prepare to hurl their spears.
The wonderful thing about printed paintings on pocket squares is that they can produce a number of different effects depending on how they are folded and creates a great topic for conversation once pulled out of the breast pocket.
