non fluxibili sed aeterno_. I think it is clear that these letters are not a mere political skit, but refer to some actual Christmas revels. The waylaying of _Iohannes Curtibiensis episcopus_ to make him ‘pay his footing’ is exactly the sort of thing that happened at the Feast of Fools, and the _non consuetudines, sed potius corruptelas_ is the very language of the decretal of 1207[1491]. But surely they are not twelfth-or early thirteenth-century revels, as they must be if ‘Robertus Grosteste’ is taken literally as the famous bishop of Lincoln[1492]. There was no _parliamenti prolocutor_, for instance, in his day. They are fourteenth-, fifteenth-, or even sixteenth-century fooling, in connexion with some _Rex Natalicius_ who adopted, to season his jest, the name of the great mediaeval legislator against all such _ludi_. At Cambridge an order of the Visitors of Edward VI in 1549 forbade the appointment of a _dominus ludorum_ in any college[1493]. But the prohibition did not endure, and more than one unsuccessful Puritan endeavour to put down Lords of Misrule is recorded by Fuller[1494]. Little, however, is known of the Cambridge Lords; their bare existence at St. John’s[1495] and Christ’s Colleges[1496]; and at Trinity the fact that they were called _imperatores_, a name on the invention of which one of the original fellows of the college, the astronomer John Dee, plumes himself[1497]. At schools such as Winchester and Eton, the functions of Lord of Misrule were naturally supplied by the Boy Bishop. At Westminster there was a _paedonomus_, and Bryan Duppa held the office early in the seventeenth century[1498]. The revels of the Inns of Court come into notice in 1422, when the _Black Book_ of Lincoln’s Inn opens with the announcement _Ceux sont les nouns de ceux qe fuerunt assignes de continuer yci le nowel_[1499]. They are mentioned in the _Paston Letters_ in 1451[1500], and in Sir Fortescue’s _De laudibus Legum Angliae_ about 1463[1501]. Space compels me to be very brief in summarizing the further records for each Inn.
