Maps are valuable not only as tools for locating places on the surface of the Earth or making spatial decisions. Secondly, they are a source of historical and other cultural elements for both their time, art, and cartography, as well as for the elements referred to in them.

Maps, therefore, are important historical documents, because in addition to geographical information, they contain technical, artistic, and semiotic elements from which information can be drawn not only about the technology, politics, art, and social life of the era in which they were created, but also about the historical accuracy of the content they project.

Maps can also have an autonomous aesthetic value. That is, they can be works of art. The book "examines" selected maps from the Lasithi Prefecture during the period from the 15th to the 19th century.
