Lorem Ipsum is simply dummy text of the printing  when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged.

Contrary to popular belief, Lorem Ipsum is not simply random text. It has roots in a piece of classical Latin literature from 45 BC, making it over 2000 years old. Richard McClintock, a Latin  Lorem Ipsum passage, and going through the cites of the word in classical literature, discovered the undoubtable source.

The standard chunk of Lorem Ipsum used since the 1500s is  Cicero are also reproduced in  translation by H. Rackham.
