Mesostic
A Mesostichon (from Greek μεσος = in the middle and στιχος = line ) is a verse or poem, in which a vertical row of letters again results in a word or sentence.
Example:
Hold it!
Behupen?
Change,
Drive off.
Another example of a Mesostichon comes from the Baroque period: John Hemelingius built in a praise poem to Arnoldus Möller the addressee's name both as acro as well as meso - and as a Tele Tikhon.
Mesosticha can also use a method of steganography, that is, the encryption text may be. John Cage developed a method to win from epic texts Mesosticha. For example, Urban Circus on Döblin's Berlin Alexanderplatz originated from work.
