One of the important stages of the First Crusade is the Battle of Dorylaeum (Eskişehir). Since ancient times, Dorylaeum has been one of the important religious centers in the Phrygia region and a settlement with underground water resources. The Crusaders, who proceeded through various routes in Europe during the First Crusade, advanced from Istanbul to Nicaia (Iznik) and from there to Dorylaeum; Here he defeated the Seljuks and moved towards Konya, Antakya and Jerusalem. It can be said that the gate of Anatolia and the road to Jerusalem were opened for the Crusaders with the Battle of Dorylaeum. Therefore, the Battle of Dorylaeum is mentioned in books about the Crusaders, and some books include images of this battle. Some of these visual examples will be discussed here.

There are examples of paintings about the Battle of Dorylaeum in the books of the clergyman and historian William of Tire (1130-1186), Godfrey of Bouillon (1058-1100), French writer, translator, religion and scientist Sébastien Mamerot (1418-1440-1490), French historian Joseph Francois Michaud (1767-1839), the historian-writer James Penny Boyd (1836-1910), French Marie de Grandmaison (1846-1933), English writer, editor, publisher, merchant and entrepreneur John Wilmot Cassell (1817-1865) and Ethel Mary-Buxton (1870-1923). The techniques of a total of twelve paintings in the ten books mentioned vary depending on the period. The artists of some of these miniature, engraving and illustration examples are known; the names of Jean Colombe (c.1430-1493), Gustave Doré (1832-1883), Edouard Zier (1856-1924), Morris Meredith Williams (1881-1973) appear. The Battle of Dorylaeum will be briefly evaluated here in terms of painting. Thus, it will shed light on the studies on Eskişehir's past from a historical and geographical perspective; it is thought that the images in such history books in general, and the images of the Crusades and wars in particular, can provide ideas for future research.
