On Wednesday 14 November the Irish Manuscripts Commission launched the latest volume in the Calendar of Papal Registers series. This volume – No. 23, Part 1 – covers the papacy of Clement VII. The volume, edited for publication by Dr Alan Macquarrie, was launched at a magnificent reception hosted by the Irish Ambassador to the Holy See, His Excellency Mr Derek Hannon.
