This work belongs to Indiana's 1962 Polygon series, small paintings featuring a numeral from 3 to 12 placed inside a polygon of the corresponding number of sides (i.e. 3-Triangle, 4-Square, etc.). The series features extensive wordplay, with references that are playful, personal, literary, and alliterative. The first example from this series, Polygon: Triangle reads “Tintinnabulation.” The word, which means “a ringing or tinkling of bells," references Edgar Allen Poe's poem “The Bells” (1849): “To the tintinnabulation that so musically wells / From the bells, bells, bells, bells.”
