Al Risha was a name quite similar to the 7 Rishi stars in Ursa Major (Itzam-Yeh).

... Proclus informs us that the fox star nibbles continuously at the thong of the yoke which holds together heaven and earth; German folklore adds that when the fox succeeds, the world will come to its end. This fox star is no other than Alcor, the small star g near zeta Ursae Majoris (in India Arundati, the common wife of the Seven Rishis, alpha-eta Ursae ...

... The story of Rip Van Winkle is set in the years before and after the American Revolutionary War. Rip Van Winkle, a villager of Dutch descent, lives in a nice village at the foot of New York's Catskill Mountains. An amiable man whose home and farm suffer from his lazy neglect, he is loved by all but his wife. One autumn day he escapes his nagging wife by wandering up the mountains. After encountering strangely dressed men, rumored to be the ghosts of Henry Hudson's crew, who are playing nine-pins, and after drinking some of their liquor, he settles down under a shady tree and falls asleep. He wakes up twenty years later and returns to his village. He finds out that his wife is dead and his close friends have died in a war or gone somewhere else. He immediately gets into trouble when he hails himself a loyal subject of King George III, not knowing that in the meantime the American Revolution has taken place. An old local recognizes him, however, and Rip's now grown daughter eventually puts him up ...

... The story is a close adaptation of Peter Klaus the Goatherd by J.C.C. Nachtigal, which is a shorter story set in a German village. The story is also similar to the ancient Jewish story about Honi M'agel who falls asleep after asking a man why he is planting a carob tree which traditionally takes 70 years to mature, making it virtually impossible to ever benefit from the tree's fruit. After this exchange, he falls asleep on the ground and is miraculously covered by a rock and remains out of sight for 70 years. When he awakens, he finds a fully mature tree and that he has a grandson. When nobody believes that he is Honi, he prays to God and God takes him from this world. Note also that the family name of Honi is also a term of geometry ('M'agel' is Hebrew for 'circle maker'), as well as the family name of Rip ('Winkel' is German for 'angle').

The story is also similar to a 3rd century AD Chinese tale of Ranka, as retold in Lionel Giles in A Gallery of Chinese Immortals. In Orkney there is a similar and ancient folklore tale linked to the Burial mound of Salt Knowe adjacent to the Ring of Brodgar. A drunken fiddler on his way home hears music from the mound. He finds a way in and finds the trowes (Trolls) having a party. He stays and plays for two hours, then makes his way home to Stenness, where he discovers fifty years have passed. The Orkney Rangers believe this may be one source for Washington Irving's tale, because his father was an Orcadian from the island of Shapinsay, and would almost certainly have often told his son the tale.

The original story was by Diogenes Laertius, an Epicurean philosopher circa early half third century, in his book On the Lives, Opinions, and Sayings of Famous Philosophers. The story is in Chapter ten in his section on the Seven Sages, who were the precursors to the first philosophers. The sage was Epimenides. Apparently Epimenides went to sleep in a cave for fifty-seven years. But unfortunately, 'he became old in as many days as he had slept years'. Although according to the different sources that Diogenes relates, Epimenides lived to be one hundred and fifty-seven years, two hundred and ninety-nine years, or one hundred and fifty-four years. A similar story is told of the Seven Sleepers of Ephesus, Christian saints who fall asleep in a cave while avoiding Roman persecution, and awake more than a century later to find that Christianity has become the religion of the Empire ...
