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 professor
at Hampden-Sydney College in Virginia, looked up one
of the more obscure Latin words, consectetur, from
a Lorem Ipsum passage, and going through the cites
of the word in classical literature, discovered the
undoubtable source. Lorem Ipsum comes from sections
1.10.32 and 1.10.33 of "de Finibus Bonorum et
Malorum" (The Extremes of Good and Evil) by Cicero,
written in 45 BC. This book is a treatise on the
theory of ethics, very popular during the
Renaissance. The first line of Lorem Ipsum, "Lorem
ipsum dolor sit amet..", comes from a line in
section 1.10.32.
