An Entertainment for Angels by Patricia Fara

By Patricia Fara

An leisure for Angels, instead of for males, one observer referred to as electrical energy, and it proved to be the main major clinical discovery of the Enlightenment. academics attracted large audiences who marveled at glowing fountains, flaming beverages, pirouetting dancers, and electrified boys. Flamboyant experimenters made chains of squaddies bounce into the air, whereas filthy rich girls titillated their admirers with a sensational electrical kiss. Optimists estimated that this unusual energy of nature may healing health problems, increase crop creation, even convey the useless again to existence. An leisure for Angels tells the tale of ways electrical energy charged the eighteenth-century mind's eye. With modern illustrations and interesting prose, Patricia Fara vividly portrays the struggles to appreciate the weird and intriguing results experiments have been generating. one of many heroes of the tale is Benjamin Franklin, popular on either side of the Atlantic as a professional on electrical energy, who brought lightning rods to guard tall constructions, pioneered innovations to regard paralyzed sufferers, and constructed the most profitable causes of this mysterious phenomenon. Others comprise Luigi Galvani, whose electric study on frogs and animals makes for grisly analyzing yet resulted in the invention of direct present electrical energy; and Alessandro Volta, who -- with Napoleon's enthusiastic help -- turned one in all Europe's best clinical practitioners and invented the world's first battery.

The first person in the line held a Leyden jar, and when the last one touched its prime conductor, they all jumped up into the air one after the other as the charge passed along them. At Versailles, Nollet entertained the king with 180 leaping soldiers; he achieved a similar feat with 200 Carthusian monks at their monastery, and later reached a record of over 600 people in his living chain. Other experimenters extended these trials by connecting people together with long wires, and electric discharges were soon 56 being transmitted around the Tuileries gardens, across Westminster Bridge, and through the River Skuylkil in North America, where Franklin’s celebratory plans included roasting an electrocuted turkey on an electrically rotating spit.

As with the electrical machine, entertainment and 55 investigative research were closely intertwined. Careful experiments soon established that instead of using water, the glass could be lined inside and out with lead foil. Provided that the wire at the top was not touched, a Leyden jar would hold its charge for hours or even days, and by connecting ten, twenty, or even a hundred jars together in batteries, the shock could be increased still further. One of these batteries, now on display at the Boerhaave museum in Leyden, carries an adjustable dial with four settings: detonating cannon, altering a compass needle, killing small animals, and melting wire.

He intended this picture not as a literal illustration of alchemical practices, but as an Enlightenment commentary on the validity of different approaches to knowledge. By focusing on phosphorus, Wright depicted research that had been taking place in England about a hundred years earlier, when the air-pump’s success was being consolidated. This had been an anxious time for natural philosophers, since they urgently needed to distance themselves from magicians, astrologers and other arcane practitioners.
