Hellenism of Ecclesiastes, Assemblyman, the congregador, the preacher, did Solomon?. This expression could be considered the synthesis of this biblical book, whose author also reflects Greek criteria on the transience of life and the enexorabilidad of death: " Vanity of vanities and all vanity ": everything is futile, frivolous, empty, meaningless. The book, written perhaps in the 6th century a. d. C., could have signed Greek skeptic or perhaps a stoic or an epicurean, and up to an Existentialist in the 20th century.
