In the era of Queen Elizabeth I (A.D. 1558- 1603), there was a priest named John Harington in England who loved literature at ordinary times and was sentenced to exile for spreading a so-called indecent story.
During the period of 1584- 159 1, he built a house in Kelston, England, where he designed the world's first toilet, which was connected to a water storage tank and installed in this house.
Pastor John Harington was very proud of this invention and named it after Ajax, the hero in Homer's epic.
Since then, Pastor John Harington has also written The Metamorphosis of chamber pot, describing the design of his toilet in detail. However, the British public at that time did not accept this invention, and they still liked to use urinals.
1775, a London watchmaker named Alexander Cummings improved Harrington's design, developed the toilet, and obtained the patent for the first time. 1
