Kirik the Novgorodian (Russian:Кирик Новгородец,romanized: Kirik Novgorodets; 1110 – after 1158) was a monk of theAntoniev Monastery and later ahieromonk in the entourage of ArchbishopNiphont of Novgorod (r. 1130–1156) famous for writing the first mathematical treatise in Eastern Slavdom, theUchenie o chislakh (Russian:Учение о числах, "Teaching on Numbers"); he also wrote entries in theNovgorod First Chronicle in the 1140s and asked some of the 152 questions of Niphont in a theological work known as theVoproshanie Kirika (Russian:Вопрошание Кирика, Вопрошание Кириково, "The Questions of Kirik").^[1] He also translated the works of PatriarchNikephoros I of Constantinople as well as the Pentateuch.

Kirik (a form of the name Kirill) wrote in theUchenie o Chislakh (in full,Uchenie im zha vedati cheloveku chisla vsekh let), that "my birthday was 26 years before now, that is 312 months, 1,300 weeks, and 9,500 without three days." Since the Uchenie is dated to 1136, his birth year would have been 1110. He is thought to be the chronicler who referred to his own ordination in theNovgorod First Chronicle under the year 1144, and to have survived Nifont (who died in Kiev in 1156), as he is thought to have written the chronicle entry in which he said that Nifont had been accused of fleeing to Novgorod after looting the archiepiscopal treasury, but defended the archbishop, asking "about this each one of us should reflect: which bishop adornedSt. Sophia, painted the porches, made an icon case, and adorned the whole outside, and in Pskov erected a stone church to the Holy Savior and another in Ladoga to St. Clement?".^[2]
