The Polyptych of Irminon, also known as the Polyptych (or Polyptyque) of St Germain-des-Pres, is an inventory of properties compiled around 823 by Irminon, the abbot of the Abbey of Saint-Germain-des-Prés. It describes the possessions of the monastery, located primarily in the Paris region, between the rivers Seine and Eure. The polyptych is renowned for its level of detail, in particular listing the names of thousands of tenants and their children.

History of the text
The text is preserved in a ninth-century manuscript, containing 20 quires, in which are described 25 villages. At least four other quires have been lost, together with almost all of a sister volume listing lands given in benefice. The repetition of a chapter shows that manuscript, in its current form, was produced from a number of working copies, and was written by around a dozen scribes. The polyptych seems to have been produced on the basis of two tours of local enquiry undertaken by monks, each one asking a different set of questions in the estates they visited.
