Of the accumulative tales, _The House that Jack Built_ illustrates the first class of tales of simple repetition. This tale takes on a new interest as a remarkable study of phonics. If any one were so happy as to discover the phonic law which governs the euphony produced by the succession of vowels in the lines of Milton's poetry, he would enjoy the same law worked out in _The House that Jack Built_. The original, as given by Halliwell in his _Nursery Rhymes of England_, is said to be a Hebrew hymn, at first written in Chaldaic. To the Hebrews of the Middle Ages it was called the _Haggadah_, and was sung to a rude chant as part of the Passover service. It first appeared in print in 1590, at Prague. Later, in Leipzig, it was published by the German scholar, Liebrecht. It begins:-- A kid, a kid, my father bought For two pieces of money: A kid, a kid, Then came the cat and ate the kid, etc. Then follow the various repetitive stanzas, the last one turning back and reacting on all the others:-- Then came the Holy One, blessed be He, And killed the angel of death, That killed the butcher, That slew the ox, That drank the water, That quenched the fire, That burned the staff, That beat the dog, That bit the cat, That ate the kid, That my father bought For two pieces of money: A kid, a kid. The remarkable similarity to _The Old Woman, and Her Pig_[8] at once proclaims the origin of that tale also. The interpretation of this tale is as follows: The kid is the Hebrews; the father by whom it was purchased, is Jehovah; the two pieces of money are Aaron and Moses; the cat is the Assyrians; the dog is the Babylonians; the staff is the Persians; the fire is the Greek Empire and Alexander; the water is the Romans; the ox is the Saracens; the butcher is the Crusaders; and the angel of death is the Turkish Power. The message of this tale is that God will take vengeance over the Turks and the Hebrews will be restored to their own land. Another tale of simple repetition, whose fairy element is the magic key, is _The Key of the Kingdom_, also found in Halliwell's _Nursery Rhymes of England_:-- This is the key of the kingdom. In that kingdom there is a city, In that city there is a town, In that town there is a street, In that street there is a lane, In that lane there is a yard, In that yard there is a house, In that house there is a room, In that room there is a bed, On that bed there is a basket, In that basket there are some flowers. Flowers in the basket, basket on the bed, bed in the room, etc.
