The Goldfinch

The Goldfinch is a painting of a chained goldfinch by Carel Fabritius, a Dutch Golden Age artist. Signed and dated 1654, it is now in the collection of the Mauritshuis in The Hague, Netherlands. The work is a trompe-l'œil oil painting on panel measuring 33.5 by 22.8 centimetres (13.2 by 9.0 in) that was once part of a larger structure, perhaps a window jamb or a protective cover. A common and colourful bird with a pleasant song, the goldfinch was used in Italian Renaissance painting as a symbol of Christian redemption and the Passion of Jesus. The Goldfinch is unusual for Dutch Golden Age paintings in the simplicity of its composition and use of illusionary techniques. After Fabritius was killed in the gunpowder explosion that destroyed much of the city of Delft in 1654, the painting was lost for more than two centuries before its rediscovery in Brussels. It plays a central role in the Pulitzer Prize–winning novel The Goldfinch by Donna Tartt, and also in its film adaptation. (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].
