The Monumenta Historica Societatis Iesu (MHSI) is a collection of scholarly volumes (157 to this day) on critically edited documents on the origin and early years of the Society of Jesus, including the life and writings of St Ignatius of Loyola.
Prompted by General Congregation XXIV of 1892, which recommended to the Superior General that writing the Society of Jesus’ history be resumed, the newly elected Luis Martin embarked on a vast project of having first published critical editions of documents on the origins of the Society available in the archives of the Order.
It could be said that this was also stimulated by the renewal of historical research methods that characterised the end of the 19th century.
Monumenta paedagogica Societatis Iesu: 1540-1616 (Ratio Studiorum and its preparatory documents): 7 volumes.
The work goes on, and is supplemented by other topical studies published in the Bibliotheca instituti historici Societatis Iesu (54 volumes).
