One of Jasper Maskelyne's regular tricks was 'The Transit of Venus.' Invented by magician David Lymer, it was marketed by magic dealer Lewis Davenports Ltd. Jasper used it for two decades from the late 1920s to the post-war period.
Coincidentally the transit of the planet Venus was first scientifically observed by English astronomer Nevil Maskelyne (no direct relation) in the 1760s. The Venus in Maskelyne’s trick references the Greek sculpture, the Venus de Milo, rather than the planet.
