The low relief on the facade of the main entrance section was created by the artist Vincent Hložník in cooperation with Peter Hložník and Ľubomír Zelina. The expressive composition is made up of allegorical figures representing the Matica slovenská organisation, poetry, the people, and lyrical motifs from literary history. 

Art historians have identified the seated figure of the woman on the left as a personification of the Matica slovenská, to whom the people came to pay tribute. The winged horse Pegasus is a symbol of poetry or the winged thoughts of literature. The relief is made of concrete panels using the same materials as the cladding for the library. 

Like the Torch statue, the relief above the three-axis entrance with awnings was anticipated in the architectural designs. The installation of the work was put at risk when Vincent Hložník became a persona non grata for the government of the day. Dušan Kuzma claimed that the authorities wanted to replace his relief with plain concrete cladding before the building was opened.

Vincent Hložník was born in Svederník (Žilina District, present-day Slovakia) on 22 October 1919. From 1937 to 1942 he studied at the Academy of Arts, Architecture and Design in Prague with professors F. Kysela and J. Novák. He studied at several schools abroad. From 1952 he taught at the Academy of Fine Arts in Bratislava. He was its rector from 1959 to 1963. After 1972 he worked as a freelance artist. He was one of the most important figures in 20th century Slovak art. He is best-known for his graphic design and illustration work. He worked on over 100 books. One of his largest projects was illustrating Dante Alighieri’s Divine Comedy. However, he also devoted himself to painting, drawing and artistic elements in architecture. He died on 10 December 1997 in Bratislava.
