In mathematics, infinity is the conceptual expression of such a numberless number. It is often symbolized by the lemniscate (also known as the lemniscate of Bernoulli), which looks something like the numeral 8 written sideways (). This symbol for infinity was first used in the 1600s by the mathematician John Wallis.
An epic is a poem; most epics started as oral tales that were passed down from generation to generation (often in the form of songs), which is why they're poems. A legend and a myth are more similar, but a myth most often explains something about the universe. So while there might be a legend about a man who slayed all the dragons, a myth would be about the man who caused it to rain, or how humans were created. Those are the basics differences.
A legend is a semi-true story, which has been passed on from person-to-person and has important meaning or symbolism for the culture in which it originates. A legend usually includes an element of truth, or is based on historic facts, but with 'mythical qualities'.sually the author is unknown and there are often many versions of the tale. Folktales comprise fables, fairy tales, old legends and even 'urban legends'. Again, some tales may have been based on a partial truth that has been lost or hidden over time.
