Associate Professor of History John Eldevik recently published a review of Keagan Brewer's Prester John: The Legend and its Sources in The Medieval Review. Brewer's volume is a collection of translated texts related to the figure of "Prester John," a legendary Christian ruler believed in the Middle Ages to possess a realm of fabulous wealth and power somewhere in the East beyond the lands of Islam.
The search for Prester John and his kingdom occupied European travellers and writers well into the early modern period. The full review can be read here.
