Fashion Meets Scientific Progress: The “Spy Fan”

Fans are so much more than fashionable accessories: They are useful for flirting, can cool heated cheeks or hide an unladylike emotion. In the wake of the Napoleonic War, their usefulness was boosted beyond the known limit when fans were made for spying, i.e. discretely observing the surrounding or other persons. I found some examples of these extraordinary devices when I visited the exhibition “Waterloo: Life & Times” of the Fan Museum in Greenwich, UK.

There were two versions of the “spy fan” around 1800: a high-tech version and a low-tech version.

The Peeping Fan

For discretion as well as stability, the holes were filled with tender net or lace. The spy holes allowed a lady to have a discrete look at what’s going on around while covering her face.
A Peeping Fan is inspiring for Regency Novel Writers and breeds plot-bunnies: Such a fan comes in handy when the heroine, an aristocratic lady, wants to hide her face from the vulgar curiosity of the mob, but at the same time needs to keep an eye on the situation. Or would a young lady in the opera box discretely look out for her secret fiancé from behind the Peeping Fan?

The Monocular Fan

fan1The high-tech “spy fan” mixed fashion with the latest scientific progress. For fans, the shape of a cockade became fashionable around 1800. The cockade fan was turned into a “spy fan” by adding a miniature spy-glass (see photo on the left). Such fans were referred to as “monocular fans” . The spy-glass was small, but its lens was efficient. Usually the spy-glass was fixed into the rivet of a cockade fan. A cockade fan allows you to peep through the spy-glass rather discreetly, as the device is in the centre of the fan and not at its head.

fan2Occasionally, brisé fans were furnished with a spy-glass. This beautiful fan (photo on the right) was made in Switzerland. The spy-glass in the rivet fits so well into the elegant design that you hardly notice it. The fan is made of pierced horn and is painted with miniature scenes of rural life. It is an idyllic design for a seemingly innocent “lady spy.” In a Regency Novel, would the heroine use this brisé fan for observing eligible bachelors at a ball in a country house? Or is she a French spy at the English seaside, secretly spying at English war ships at the harbour?

The sticks are shaped like classical urns – a rather morbid design. The spy-glass is bigger than the one of the Swiss fan (above), but disguised by being of the same colour as the horn sticks.

Why Fashion and Science Could Meet

Spy-glasses were developed in the 17th century. Their quality improved in 1733 with the invention of the achromatic lens. Achromatic lenses were expensive, and they were patented. The patent was held by the optician John Dollond. When his patent expired in 1772, prices for lenses dropped by half. Mass production and the development of “fashionable scientific toys” could begin. High society was fascinated with miniature spy-glasses. Spy-glasses were built in accessories for men (snuff boxes) and women (fans) alike.

    • Thank you for the kind comment. The monocular fans are indeed amazing. I was thrilled to find them at the special exhibition of the Fan Museum in Greenwich.

      Thank you very much for adding my website to your list. I hope you enjoy readind “Regency Explorer”. The topics vary from writing to research and first-hand experience.

  1. Many a plot bunny jostling here! Why, however, do I think that they were more used by the terminally nosy than by spies of serious intent…however, I can also see one being used by a high class blackmailer to get a closer look at potential victims, especially if she has learned to read lips, and there may be room for one of these for an accomplice in a Jane and Caleb book I have in mind…. or in Scarlet Pimpernel fan-fiction! thanks for this, Anna, for a fascinating post on an intriguing little device and one which begs to be used!

    • Brilliant, a high class blackmailer is a very good plot bunny. She will be the villain, of course, trying to find prevent the happy ending between hero an heroine.
      If you find room for the fan in Jane and Caleb book, feel free to share it here.
