This chapter offers a reconstruction of the curious story of how the Danish Archbishop, Eskil of Lund, lost a large amount of money that he had placed in the custody of his friend, Abbot Ernis, at the abbey of St Victor in Paris. The case of Eskil's lost money has been dealt with by other scholars before, though often only in passing. Ernis is still a major player at the royal court and in 1165 he has the honour of becoming the godfather of the future king, Philip Augustus. The problem in Ernis' financial transactions may lie in this aspect: not only did he mortgage the abbey's property and estates, he rented out the profit of prospective future revenue. Thus, since it did not contradict any existing regulation, there was nothing illegal as such about the Victorine deposit-banking scheme, that is, as long as it worked, most crucially, as long as the abbey remained solvent.
