Text in Danish. "Det persiske felttog -- Anabasis" (Anabasis -- March up Country) is the best known work of the Old Greek philosopher, historian and essayist, Xenophon (c. 430-354 BC). Anabasis literally means ''the march up country''. The book renders the fate suffered by the army of 10,000 Greek mercenaries, when it was hired to support an internal attempted coup within the royal family in the mighty Persian reign 400 BC. The mercenaries stranded deep into Persia without guides or supplies. The seven books of the writing tell of the incredible hardships and sufferings the army had to go through during the retreat back through Armenia and Turkey in order to reach the Black Sea and the Greek world. Xenophon''s gripping work belongs among the Great Classics of European historiography, and is here translated in its entirety into idiomatic, modern Danish for the first time. The book is provided with an illuminating introduction, covering central issues such as the literary purpose of the work, Greek military affairs and religion. Furthermore, there is an entire register of the persons and localities in the text, plus a number of explanatory notes. Finally, the work is provided with several maps, plates and illustrations, explaining complicated passages together with a series of colour photographs of relevant landscapes.
