Y'Raka

From Memory Alpha, the free Star Trek reference

Y'Raka was a famous artist who had a pessimistic nature to his work.

In 2370, Benjamin Sisko referred to Y'Raka, along with similarily natured Vincent Van Gogh and Beckett as an example of pessimistic artists who created something of great worth. Contrary to this fact, Gideon Seyetik described their works as "dreary, dark and depressing". (DS9: "Second Sight")
