In the ancient Greek myth The Odyssey we read the epic tale of Odysseus. Odysseus was the valiant warrior who fought so bravely in the Trojan War. But, according to legend, his homeward journey after that war was interrupted for many years as the gods had decided to test Odysseus' true mettle through a series of trials. His journeys carried him far and wide as he encountered mythic beasts and lands, many of which have passed into common parlance: the Cyclops, the Procrustean bed, Scylla and Charybdis, the sirens' voices.

Meanwhile, back at his home, Odysseus' wife and family presume he must have died en route back from Troy. Finally, however, the day came when the gods released Odysseus and he arrives back home at last. But instead of simply waltzing through the front door and crying out some Greek equivalent of, "Honey, I'm home!" Odysseus decides that he wants to determine if anything has changed during his long absence. Did his wife still love him? Had she been faithful? In order to find out, Odysseus disguises himself so as to approach his home looking like a stranger in need of temporary lodging.

The housekeeper, Euryclea, welcomes the apparent traveler and performs for him the then-standard practice of foot-washing. As she does so, Euryclea regales the stranger with anecdotes about her long-lost master, Odysseus, whom she had also served as a nurse when he was young. She told the traveler about how long her master has been missing and she noted, too, that by then Odysseus would be about the same age and of about the same build as the man whose feet she was washing. Now when Odysseus had been a young boy, he was once gored by a wild boar, leaving a nasty scar on his leg. As Euryclea went about her servile task, suddenly her hand brushed against that old scar and instantly her eyes were opened and she recognized, with great joy, her beloved friend and master!
