Reply of the Zaporozhian Cossacks depicts a supposedly historical tableau, set in 1676, and based on the legend of Cossacks sending a reply to an ultimatum of the Sultan of the Ottoman Empire, Mehmed IV. The original reply, if it ever existed, has not survived; however, in the 1870s an amateur ethnographer from Yekaterinoslav (today Dnipro), Ya. Novitsky, found a copy made in the 18th century.
