Am SO excited about today's entry, which opens a door to a realm of domestic history I hadn't encountered before.
The round screen above, currently up for auction on eBay, originated in Venice. Unlike most of the handheld fans we know, it was not used to cool the face by displacing the air. Instead, it shielded the face from the direct heat of a fire, which, not too long ago, was the only way to keep a house warm.
A fire could redden the carefully cultivated pallor of upper-class women--and worse. The caption that describes this pair of puzzle-inscribed face screens (from the Puzzle Museum) elaborates the extent of potential damage:

Just as evocative, in a different way, is the wonderfully shabby floral on the reverse of the fan, reminiscent of lush Venetian velvet tapestries that have withstood centuries of rising damp and fog . . .
(with many thanks to the Puzzle Museum and especially to Anti-qs for providing the wonderful photos of the Venetian screen.)
