Gondolin—the very word conjures heart-wracking glimpses of the vanished past. Elrond’s father Eärendil was born there, the swords that Bilbo and Gandalf took from the troll-hoard were forged there, Gimli sang of its mighty king, Galadriel remembered it from before it fell. But what was Gondolin? In this episode, Professor Rachel Fulton Brown follows Tuor, son of Huor—or was it son of Peleg?—through the mountain gates—were there seven or only one?—to the hidden city of Turgon with its walls of white and fountains of song. On the journey, we discover the deep roots of Tolkien’s whole legendarium—the untold story upon which all other stories depend.
