Joaquim Pi i Margal was an important Spanish engraver and draughtsman from Barcelona. He began his studies at the School of Fine Arts in Barcelona and was a disciple of the eminent engraver Antonio Roca, finishing his training as an engraver at the Imperial Academy of Paris, specializing in steel engraving, a discipline not widely used in Spain.
On his return he published the Complete Works of Flaxman, a work that earned him a very favorable artistic reputation, thanks to which he obtained work in the most important engraving projects of the time in Spain, such as the collection of Architectural Monuments of Spain, from which he engraved several plates. He collaborated with the Spanish Museum of Antiquities, published several works by foreign cartoonists and his own drawings such as the Triumph of the Religion of Christ by the German artist Joseph Fürich, or the Universal Library of his own creation.
He obtained the chair of engraving at the School of Fine Arts of Barcelona and was deputy of courts in 1873. Throughout his career he received two medals at the National Exhibitions of Fine Arts in 1860 and 1862.
