What is proper art?

In Baroda, a student was arrested for rendering improper art.

The New York Times reports--

The tempest began on May 9 when a lawyer accompanied by police officers and television news crews marched into the art department at the respected Maharaja Sayajirao University, a state-run institution in Vadodara, in western Gujarat state. (Gujarat’s elected government is led by the Hindu-nationalist Bharatiya Janata Party.)

The lawyer, Niraj Jain, based locally and affiliated with the party, said he was aggrieved by several works exhibited on a wall in the department library, including a painting — or rather a digital enlargement of a painted work — depicting a female form wielding weapons in her many arms, evoking a goddess from the Hindu pantheon, and giving birth. It was the final-year art project by Chandramohan, a graduate student who goes by one name.
