Monocondyl is a type of ligature . A word or several words at once are written in one go, without lifting the pen from the paper. In this case, the letters are intricately intertwined, extra connecting lines appear. Words in a sentence lose their usual breakdown and, as a result, the styles of individual letters are hardly distinguished.
An example of monocondyl can be the first word in the title of Peter I (see. Fig.)  .
Samples of such a letter can be traced in the sources of the XVI century:
- Manuscript Undolsk N 53 (Psalter with Examination), (former Rumyantsevsky Muses.) And
- Vyazemsky Gospel , 1527
- Fully deciphering the titles, see Titles in ancient Russian cryptographies
