This manuscript recounts in words and pictures the lives and miraculous after-lives of two aristocratic brothers, Aimo and Vermondo, who lived in Milan at the end of the 700s (the text is written in Latin, with the title Legenda venerabilium virorum Aymonis et Vermondi). It may have belonged to the church that they founded, where their tombs were located and which also owned another illustrated manuscript of their lives. The book would have served as a document confirming the miraculous power of the saintly brothers' mortal remains. It might otherwise have belonged to a devout follower of Aimo and Vermondo. Those who sought miraculous cures or made pilgrimages to a saint's shrine often owned copies of that saint's biography.
