The story of Tamerlane (Timur - Leng) available to the English speaking world has dealt mostly with his exploits. Translations of reports of his military prowness were made from those affected by the results of his conquests. Contemoraneous reports were tainted by terror or exultation, depending upon how the writer fared in the battles.It was left to Marlowe to reveal the character of the man, from a distance of time and culture, in his plays called "Tamburlaine." Unfortunately, although the psychological insight was telling, many of the facts were wrong. Even Gibbon gave his character less attention than this world conqueror or "Scourge of God" deserved.We are fortunate to have on hand the dedicated work of Roy Stier, whose meticulous research of valuble original texts, permits the reader to form his own conclusions.
