Illustration with Aeneas holding the Golden Bough

The Golden Bough is a fantastical object in the Aeneid, an epic poem by the 1st century BCE Roman poet Virgil. The Trojan hero Aeneas is tasked to find the bough and remove it from its host tree to prove his divine favour before his journey into the Underworld. It briefly resists as he does so – the implications of which have been widely debated in scholarship. In the medieval period, commentators often interpreted the bough allegorically and as a symbol of wisdom. More recent scholars have viewed the episode as reflecting Virgil's ambivalence towards the Roman Empire, and connected it to the deaths of two of Aeneas's antagonists, Dido and Turnus. The bough has been widely referenced in art and literature. It was used by James Frazer for the title of his 1890 work on comparative religion, is recalled in Dante's Divine Comedy, and was the subject of an 1834 painting by J. M. W. Turner. It is also a recurring motif in the "Byzantium" poems of W. B. Yeats and in the poetry of Seamus Heaney. (Full article...)

Why you should extend your general knowledge:

There are many reasons why one should or wants to extend his knowledge.
First you should consider that "general knowledge" is knowledge which a group of humans - who belong together regional, temporal or otherwise - owns. Thus, it describes a basic understanding of specific categories of knowledge.

As the English philosopher Francis Bacon said before: "Wisdom is Power" [Bacon 1597].
