"Citius, Altius, Fortius" – Pie-IX Metro Station, Montréal, Québec

Pie-IX is a station on the Green Line of the Montreal Metro rapid transit system operated by the Société de transport de Montréal (STM). It is in the district of Hochelaga-Maisonneuve in the borough of Mercier–Hochelaga-Maisonneuve in Montreal, Quebec, Canada. This station is named for Pie-IX Boulevard (pronounced pea neuf). This street was named in 1912 for Pope Pius IX (1792–1878), elected Pope in 1846. English speakers often humorously refer to either the street or Metro station as "Pie Nine."

Pie-IX station was inaugurated on June 6, 1976, as part of the extension of the Green Line to Honoré-Beaugrand, in time for the 1976 Summer Olympics. The station includes a long mural in concrete and aluminum by Jordi Bonet entitled Citius, Altius, Fortius ("stronger, higher, faster" – the Olympic motto).

Born in Barcelona in 1932, Jordi Bonet was turned to art early in life by the loss of his right arm. His childhood would be marked by the Spanish Civil War. He studied art in Barcelona. He began working in paint and ceramic before expanding his focus to include metal and concrete reliefs.

After studying in Barcelona, he settled in Quebec in 1954, where he continued his studies. Over the next twenty years, he created more than a hundred murals in ceramic, cement, bronze, and aluminum across the world, and associated with the likes of Salvador Dalí. Much of his work was in sacred and liturgical art. He won a place among Quebec's most important artists before his early death of leukemia at age 47.
