The book "Land and Sea Through the Ages" by Wilhelm Belsche is a study of the relationship between natural conditions and cultural traditions in different regions of the world during historical periods. The author investigates how the geographical location of different territories affects the development of society, economy, culture and national character of peoples. The book examines how the borders and interests of states changed depending on their position on the world map in different historical eras. Great attention is paid to human interaction with various aspects of nature - land and sea, their influence on the formation of cultural values and traditions. "Land and Sea Through the Ages" is considered one of the key works of the author in anthropogeography and cultural history, which is still relevant for the study of the relationship between man and nature.
