Leviathan is a giant sea beast narrated in the Bible. His creation by God is found in Genesis and Job describes his physical appearance as resembling a dragon. Beams of fire come out of his mouth; sparks of fire proceed. Smoke comes out of their nostrils, as if from a boiling pot or cauldron. 

Liber Floridus is a medieval encyclopedia that was compiled between 1090 and 1120 by Lambert, canon of Saint-Omer. The text compiles extracts from some 192 different works. Lambert's medieval encyclopedia contains a universal history, with a chronological record of events until the year 1119.

Lambert wrote Liber Floridus originally in Latin, and later it was translated into French as Le Livre.
