This book is about the Pontus as seen and described by Western travellers of the 19th century. The information offered by these travellers was examined in the process of determining on the map the route of the Retreat of the Ten Thousand, as narrated by Xenophon in his Anabasis. The problems associated with this determination are addressed in a book written in parallel with the present one (Iordanis Paradeisopoulos (2023), Xenophon’s Riddle. Also in Greek, Ιορδάνης Παραδεισόπουλος (2023), Ο γρίφος του Ξενοφώντος). Chapters from nine books are presented here. The books, written in English, are in chronological order those of Kinneir (1918), Porter (1822), Smith (1834), Hamilton (1842), Southgate (1850), Layard (1853), Curzon (1853), Tozer (1881), and Lynch (1901). Two articles are also presented, writthen by Brant (1836), and Briot (1870), and published in the Journal of the Royal Geographical Society of London. Additionally, excerpts are provided from the Greek text of historians narrating the sack of Trebizond by the Goths in 258 AD (Zosimus), and the conquest of Trebizond by the Ottomans in 1461 (Sphrantzes, Critobulus, Chalkokondyles, Ducas, Pseudo-Sphrantzes, Amiroutzes, Ecthesis Chronica). These excerpts are provided both in the original and in our English translation.
