HICKORY, DICKORY DOCKThe original rhyme

Hickory, dickory, dock,
The mouse ran up the clock.
The clock struck one,
The mouse ran down,
Hickory, dickory, dock

The original rhyme was recorded in 1744 in Tommy Thumb's Pretty Song Book. The lines were Hickere, Dickere Dock.  The more modern, Dickery Dock was recorded in Mother Goose's Melody  two decades later. Like all nursery rhymes, the first recorded documentation may NOT have been the invention of the rhyme which may or may not date back further.  This rhyme might have been some sort of rhyme to help children learn time.  On an online source http://www.dltk-teach.com/rhymes/hickory/words.htm more verses are added, but this source does not
