From 1343 Closener was the custodian of the Marienaltar in Strasbourg Cathedral, where later he served as vicar of the large choir.
[3] His most famous work is his Chronicle (full title Kronika aller der bebeste und aller der romeschen keisere, die sit Cristus gebürte sint gewesen).
[3] It is written in High German and connects the history of his city, its region and its bishops with the wider world of the Holy Roman Empire.
[2] His sources included Martin von Troppau, a version of the Sächsische Weltchronik and the Bellum Waltherianum of his predecessor, Ellenhard of Strasbourg, which he translated and incorporated.
[3] Closener also compiled a German–Latin dictionary, the Vocabularium seu nomenclator, and a now lost order of worship for Strasbourg Cathedral around 1364, Directorium chori.
