In the late XIX - early XX centuries A.V. Kruglov enjoyed fame, although he lived financially hard and was often sick. Alexander Vasilievich was published in periodicals, published a number of books ("Old and New," "Lord Zemtsy," "Provincial Tales," "Unwise Happiness," etc.) He wrote essays "Vologda and the Vologda Territory," "Lacemaker," etc. Kruglov's first major work was an essay about M.V. Lomonosov - written in Vologda in 1870, when the author was not yet 18 years old. Subsequently, the essay was published as a separate brochure for schoolchildren and withstood eight editions. Kruglov's great merit is that he introduced the then readers to the Komi people.
