The icons that do remain show a mixture of traditional Rus style, Palaeologus-Byzantine style (prominent previously in Kiev), and European Romanesque and Gothic style. The artists of Novgorod, and their audience, favored saints who provided protection mostly related to the economy. The Prophet Elijah was the lord of thunder who provided rain for the peasants' fields. Saint George, Saint Blaise, and Saints Florus and Laurus all provided some manner of protection over the fields or the animals and herds of the peasants. Saint Paraskeva Pyatnitsa and Saint Anastasia both protected trade and merchants. Saint Nicholas was the patron of carpenters and protected travelers and the suffering. Both Saint Nicholas and the Prophet Elijah also offer protection from fires. Fires were commonplace in the fields and on the streets of the city. Depictions of these saints retained popularity throughout the entire reign of the Republic. But in the beginning of the 14th century another icon became prominent in the city: the Virgin of Mercy. This icon commemorates the appearance of the Virgin Mary to Andrew Yurodivyi and Epifanii. During this appearance, Mary prays for humankind. The art movement of Novgorod was essentially destroyed by Moscow after 1478, when a more uniform method for iconography was established throughout Russia.
