Once into the time Initials
Initial letters in book of poems written by Bojana Ristic. Cyrillic.

 In a written or published work, an initial is a letter at the beginning of a work, a chapter, or a paragraph that is larger than the rest of the text. The word is derived from the Latin initialis, which means standing at the beginning. An initial often is several lines in height and in older books or manuscripts, sometimes ornately decorated.
