Fame can come from many sources.
Fame and greatness may not be precisely the same, but this statement is equally true of fame. Fame can come from being born in a famous family or from achievement or accident. A poet may achieve fame through education, from being born in the right place or having a timely message. It may come through charisma or Intelligence or from a knack with words. Homer was among the most famous poets of his day and in great demand among wealthy patrons to recite his extensive repertoire.
