Published here is a critical edition of Augustine’s Sermons 293 and 299, the first edition since the Maurists. Sermon 293 was preached in Carthage on the 24th of June 413, feast of John the Baptist, at a time when infant baptism was a controversial question. Sermon 299 was delivered on the 29th of June, in honour of Peter and Paul : its manuscript transmission and thematic likeness with Sermon 293 suggest that it was preached, according to Pierre-Marie Hombert’s hypothesis, in the same year in the same city, not five years later. Both texts, numbered among the longest of the De sanctis sermons, contradict Pelagian theses about the origin of death and the notion of human impeccability.

Despite the ideal of dispossession, absolute poverty and the total absence of links with possession and human beings which shaped the myth of the monastic desert, the monastic economy and its management were very similar to the secular economic system, in that both were organised by networks based on families.This article tackles how and where material assets were produced and administered in Egyptian monasteries between the fourth and eighth centuries (the diakonia), and who was responsible for this function (the oikonomos). The history of monasticism is materially related to the institutionalisation of the society’s cultural and material systems of production. Consequently the economy was also transformed by monastic practices: history is linked to the definition and the successful affirmation of the figure of the oikonomos, the steward in charge of everyday life in monasteries.
