Dissolving views were a popular type of 19th century magic lantern show exhibiting the gradual transition from one projected image to another.
[1] The subject and the effect of magic lantern dissolving views is similar to the popular Diorama theatre paintings which originated in Paris in 1822.
[3] Another popular example has a soldier sleeping or daydreaming on the battlefield, with dissolving views displaying several of his dreams about home above his head.
[4][5] Information about De Philipsthal's activities after 1804 is limited, so it remains unclear whether he did incorporate the effect in his shows before other lanternists developed their own versions.
However, an 1812 newspaper about a London performance indicates that De Philipsthal presented "a series of landscapes (in imitation of moonlight), which insensibly change to various scenes producing a very magical effect".
Probably the first biunial lantern, dubbed the "Biscenascope" was made by the optician Mr. Clarke and presented at the Royal Adelaide Gallery in London on December 5, 1840.
