## Author

Bevis Longstreth is a writer of historical novels. He has written three novels: Spindle and Bow (2005), Return of the Shade (2009), and Boats Against the Current (2016). Spindle and Bow is a story of love and adventure set in the 5th Century BC. The settings span some 3,000 miles (4,800 km), from the ancient city of Sardis, at the western edge of the Persian Empire in Anatolia to the Scythian village of Pazyryk in the Altai Mountains of southwestern Siberia. The story answers many mysteries surrounding the Pazyryk, a perfectly preserved pile carpet measuring about six feet square discovered in 1949 in a royal Scythian tomb with a man, a woman and nine horses cut down in the prime of life. Scholars consider the Pazyryk a masterpiece of weaving technique and artistry dating from the Iron Age, some 400 years before the birth of Christ. It remains today the world's oldest pile carpet. Longstreth is meticulous in his use of facts about the period and the carpet itself, using the accredited available historical sources. The carpet is now on view in the Hermitage Museum in St. Petersburg.
Return of the Shade is the story of Queen Parysatis of Ancient Persia., a Queen and Queen Mother of the Persian Empire at its peak of power. She lived for about 60 years from around 444 to 384 BC, one and a half millennia ago. She was the purest strain of Persian, a direct descendant of Cyrus the Great, founder of the Achaemenid dynasty and of the Persian Empire, which lasted 220 years from 550 to 330 BC – a dynasty that brought stability, prosperity and a flourishing civilization to what we now call the Middle East and beyond. In its day, the largest and most powerful Empire the world had ever seen. It extended from the Indus River to North Africa, from the Aral Sea to the Persian Gulf, all told one million square miles. The Persian Empire had everything under the sun. Everything, that is, except a single historian to preserve for posterity its highs and lows. As seen through the eyes Greek historians, the Persians were weak and effeminate: a barbaric and despotic foil against which the courage, discipline, democracy, and culture of the Greek civilization could be set.
Longstreth says of Parysatis, "She was a forgotten Queen in a forgotten Empire, dismissed by the Greeks as hopelessly cruel. By working with the few facts about her that had been recorded by Greek historians such as Plutarch and Ctesias, it was possible -- much as it would be to divine an entire puzzle from a few important pieces -- to fill in the empty spaces with imagined accounts of Parysatis’ life: a life endowed with great power and the instinct to know how to use it; a life fraught with the drama of the Achaemenids, a royal line beset with patricides, fratricides and other wicked episodes so typical of the ruling classes at all points of the compass. Here, too, was a chance to illuminate an Empire cast in darkness by Greek writers."
Boats Against the Current charts the struggles of six lives braided together in the Great Depression, with FDR's New Deal and its Works Progress Administration serving as armature for the story. These fictional characters blend with many historical figures, including Hallie Flanagan, head of the WPA's famous Theatre Project, Huey Long, the tyrant from Louisiana, and William Allen White, the editor and owner of The Emporia Gazette in Kansas.
Longstreth is also the author of Modern Investment Management and the Prudent Man Rule (Oxford University Press, 1986), a book seeking to modernize the law governing investment management by fiduciaries.
