Jan z Lublina, or Joannis de Lublin, was a Polish composer and organist who lived in the first half of the 16th century.
Not much is known about his life but he was a member of the Order of Canons Regular of the Lateran, circa 1540, and was possibly the organist at the convent in Kraśnik, near Lublin.
From 1537 to 1548, he created the famous organ tablature, whose title is Tabulatura Ioannis de Lyublyn Canonic[orum] Reg[u]lariu[m] de Crasnyk.
This is the largest organ tablature in the world (more than 350 compositions and a theoretical treatise) and one of the earliest.
It contains several compositions by Nicolaus Cracoviensis, as well as numerous intabulations of works written by Josquin, Heinrich Finck, Janequin, Ludwig Senfl, Claudin de Sermisy, Philippe Verdelot, Johann Walter, etc.
