Diana and her deer were the very last characters to appear in The Pastoral Symphony segment. Here, she uses the crescent moon as a bow to fire an arrow to spread stars across the sky to announce the night, ending the segment.
At the end of the 1990 reissue trailer for Fantasia's 50th anniversary, when Diana fired her star arrow across the night sky, its trail formed "Walt Disney's" while the stars that fell from it formed "Fantasia".
Diana is the goddess' Roman name. In Greece, she is called Artemis.
