The tragedy of planes hijacked by terrorists intentionally crashing into the twin towers at the World Trade Center on September 11, 2001, is among the century's most memorable and traumatic events.
The New Britain Museum of American Art commissioned Graydon Parrish to paint an 18 foot-long mural commemorating the events. The central figures of his allegorical painting are the twins, Terror and Tragedy, representing the agony of the two falling towers.
I attended a lecture by Parrish about his painting at NBMAA on September 11, 2014. (These photos are from that time.) Parrish will lecture about it again today, but the lecture is sold out. It is available as a virtual event, but I didn't register. The mural was displayed in recent years but is now back until year end.
