The archaeologist D. G. Hogarth (1862–1927) was, when he died, keeper of the Ashmolean Museum and president of the Royal Geographical Society. During the First World War he was acting director of the Arab Bureau in Cairo, where he was instrumental in launching the Arab Revolt, in which T. E. Lawrence, a protégé of his, played so prominent a part. This book, published in 1904 as the Hejaz railway was being built, is a summary of earlier explorations in the Arabian peninsula, by both Muslim and European travellers. Hogarth's first visit to Arabia was not made until 1916, when he travelled to Jeddah with £10,000 in gold to finance the revolt; this book is instead based on his extensive reading of travel literature, included in a bibliography for each chapter. It is thus interesting for its historiographical analysis as well as a background to Hogarth's subsequent political involvement with the region.
