Coloured engraving by M Dubourg after an original work by J H Clark showing the fortres in Green Park which was transformed from the Temple of Discorde into the Temple of Concorde, in honour of the Grand Jubilee celebrations on 1 August 1814. The Prince Regent (and future King George IV) declared a Grand Jubilee in celebration of the recent victory over Napoleon and a centenary of Hanoverian rule. Sir William Congreve (1772-1828) devised a mechanism to enable the metamorphosis, which was revealed momentarily amid a cloud of fireworks. Whilst the fireworks display continued, English aeronaut Windham Sadler ascended in his balloon and dropped favors and programmes to the crowd below. Published by Edward Orme on 12 August 1814. Dimensions: 298mm x 407mm.
