This painting is one of a series of works Young-Il Ahn made as a memorial to the terrorist attacks on the United States on September 11, 2001. Ahn married his wife Soraya on September 09th, 2001, and days later September 11th would rock them as it did many Americans. Soraya's three grown daughters had flown to California from New York for the wedding; this close brush with the attacks charged the event with all the greater weight for Ahn and his new family. These mysterious, grim paintings emanate a sense of pain and sorrow, rather unlike the jovial rhythms of his other canvases. The September 11th series is an extension of Young-Il Ahn's Self-Reflection series. One of his most personal bodies of work, it shares many of the organizational hallmarks of his Water paintings, including compositional reliance on a grid, impasto marks, and similarly worked surfaces. But the autobiographical content of these paintings lends them a unique character within his oeuvre.
Woven into the abstract grids of the Self-Reflection paintings are a series of linguistic symbols, including references to the logically ordered, alphabetical writing called Hangul, as well as logographic symbols borrowed from Chinese called Hanja.
