Later, many of his paintings and works on paper moved into "romantic symbolism", and their titles can be interpreted visually through shapes and forms and words. Twombly often quoted the poet Stéphane Mallarmé, as well as many classical myths and allegories in his works. Examples of this are his "Apollo and The Artist" and a series of eight drawings consisting solely of inscriptions of the word "VIRGIL". In a 1994 retrospective, curator Kirk Varnedoe described Twombly's work as “influential among artists, discomfiting to many critics and truculently difficult not just for a broad public, but for sophisticated initiates of postwar art as well". After acquiring Twombly's "Three Studies from the Temeraire" (1998–99), the Director of the Art Gallery of New South Wales said "sometimes people need a little bit of help in recognising a great work of art that might be a bit unfamiliar". He is said to have influenced younger artists such as Anselm Kiefer, Francesco Clemente, and Julian Schnabel.
