Nikiforos Gregoras from Heraclea of Pontus is one of the most significant Byzantine scholars and scientists of the 14th century. He left us a rich body of work, in which the influence and detailed knowledge of ancient and later Greek literature is evident.

Through his work, a wealth of geographical elements and information emerges. This particular book examines the wide range of Nikiforos Gregoras's geographical world, the natural as well as the human-built environment of a specific era in relation to historical events, providing a comprehensive picture of a world that lives and moves in the penultimate Byzantine century.

The book fills an important gap in the field of Byzantine geography, which today attracts increasing interest from both researchers and the general reading public.
