The land upside down: Saudi illustrated for children Description Samuel Zwemer (1867-1952) was an American missionary who became known as the "Apostle of Islam" for his tireless, and not always successful, evangelization efforts in Islamic countries. He attended Hope College in Holland, Michigan, and New Brunswick Theological Seminary in New Jersey. In 1889, he and a classmate founded the American Arabian Mission, who later received the patronage of the Reformed Church. The following year, he left for the Arabian Peninsula. In 1896, he met Amy Wilkes (died 1937), a nurse and Australian missionary whom he married. The Zwemers spent 15 years in the region. Together they sold bibles, established missions in hospitals and in 1899 They founded a small school in Bahrain. The land upside down was the first of two illustrated children's books, written by the couple. The work focused on attracting young people for missionary work. In the preface, the Zwemers describe the collection of stories as an "upside book down; there is no order in relation to chapters and you can start reading anywhere. "The chapters include a description of the geography of the Arabian Peninsula, as well as issues of Arab customs, and domestic habits, clothing, prayer rituals, Arab proverbs and the slave trade. The book contains 35 photographs, illustrations and maps.
