thumb|right|Reconstructed nyctograph, with scale demonstrated by a 5 euro cent. Nyctography (in Nyctography: ) is a form of substitution cipher writing created by Lewis Carroll (Charles Lutwidge Dodgson) in 1891. It is written with a nyctograph (a device invented by Carroll) and uses a system of dots and strokes all based on a dot placed in the upper left corner. Using the Nyctograph, one could quickly jot down ideas or notes without the aid of light. Carroll invented the Nyctograph and Nyctography as he was often awakened during the night with thoughts that needed to be written down at once,

Tool for writing / reading with the nyctographic alphabet (which can be read in the dark) designed by Lewis Carroll.
dcode.fr →Tool for writing / reading with the nyctographic alphabet (which can be read in the dark) designed by Lewis Carroll. Lewis Carroll's Nyctographic alphabet is a writing system composed of special square-based characters, which represent the numbers or letters of the alphabet. To decode a message written using Lewis Carroll's nyctographic alphabet, reverse the encoding process by identifying the symbols in the encrypted message and replacing them with the corresponding letters from the normal alphabet. Lewis Carroll's Nyctographic alphabet is recognizable thanks to its basic square structure, its lines at the edge of the square and its dots positioned at the corners of the square. Any references to Charles Lutwidge Dodgson, aka Lewis Carroll, or his writings like Alice in Wonderland are clues. dCode retains ownership of the "Nyctography Lewis Carroll" source code.

Nyctography (in Nyctography: ) is a form of substitution cipher writing created by Lewis Carroll (Charles Lutwidge Dodgson) in 1891.

Using the Nyctograph, one could quickly jot down ideas or notes without the aid of light. Carroll invented the Nyctograph and Nyctography as he was often awakened during the night with thoughts that needed to be written down at once, and didn't want to go through the lengthy process of lighting a lamp only to have to then extinguish it.
==The nyctograph== The device consisted of a gridded card with sixteen square holes, each a quarter inch wide, and system of symbols representing an alphabet of Carroll's design, which could then be transcribed the following day.
