A History of Medieval Myth and Legend
From Tardis Wiki, the free Doctor Who reference
A History of the Medieval Myth and Legend was a history book written by Angus Heatherington about medieval myths and legends. It included the myth of "Irongron's Troll", which spawned from the true events surrounding the Sontaran Jingo Linx in the Middle Ages. An excerpt and illustration from A History of Medieval Myth and Legend were among the documents included by Justin Richards in his alien exposé The Secret Lives of Monsters.
