Dear Colleagues: I am working on a paper concerning Matthew Paris and the Parisian monastic colleges and need your help in understanding the significance of a certain passage. Matthew Paris writes (in Richard Vaughan's translation): From the incarnation of the Lord twenty-five half-centuries have elapsed. Nor does it seem that Easter has fallen on its own day, namely the sixth of the kalends of April [27 March], in any jubilee year, namely the fiftieth, except in this last year. I am interested in the notion of Easter falling on its own day. What does this mean and what is its signficance? I thought for a moment it meant that Easter and the feast of the Annunciation [25 March] fell on the same day in 1250, which conjunction would presage the end of the world. But this does not seem to be the case in this passage. Also, I have lost from my favorites the wonderful calendar programs developed by members of the group. If the URLs could be sent, I'd be very appreciative. Thomas Sullivan, OSB %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
