It is set to the tune of ‘Starry Starry Night‚’ a song written by Don McLean. McLean wrote the song as a tribute to Van Gogh and told the story of Van Gogh’s life through his own eyes. McLean portrays Van Gogh as somewhat of a tormented soul who took his own life. I could almost feel Van Gogh’s pain through the mixture of visual and

How does Shakespeare present the theme of deception in the first two acts of Twelfth night? Shakespeare’s Twelfth night‚ focuses mainly on the theme of deception in both main plot and the sub-plot.

The contoured forms in this piece of artwork convey emotion and are means
