[64] Spelman (_Glossarium Archaeologicum_, s.v.) derives our _Maundy_ from _maund_, ‘a basket,’ because gifts for the poor were carried in baskets; and this derivation has attained some popularity. But there is little to support it. In Germany from the later mediaeval period _Der grüne Donnerstag_ (Green Thursday) has been the popular name of the day. No entirely satisfactory explanation of the term has been offered. There is no question that in several German churches green vestments were worn by the priest and his ministers at the Mass of Maundy Thursday. [65] _Chr. Worship_, E. tr., p. 248.

[69] In 1892 the Protestant Episcopal Church in the United States of America introduced into its Prayer Book the Transfiguration (Aug. 6) as a red-letter day with proper Lessons, Collect, Epistle, and Gospel.

[74] For details the student may consult Baillet, tom. IX. ii. 152-158. [75] Twysden’s _Decem. Scriptores_, col. 1383. [76] The date of this Council is sometimes placed as early as A.D. 656. [77] [See esp. the _Protevangelium Jacobi_. Edd.] [78] In the printed Sarum books the Assumption was a ‘principal double’; the Purification and Nativity ‘greater doubles’; and the Annunciation a ‘lesser double.’ [79] For these, and varieties as to the day of observance, see Grotefend, _Zeitrechnung des deutsch. Mittelalters u. der Neuzeit_. [80] [See the _Protevangelium_ (cc. 7, 8). Edd.] [81] [See however Gasquet and Bishop, _Bosworth Psalter_, pp. 49 f.

[89] In the (so-called) Hieronymian Martyrology the entry at Jan. 18 runs ‘Dedicatio Cathedrae S. Petri Apostoli, quâ primo Romae sedit.’ [90] The student may consult the scholarly article of Dr Sinker on ‘Peter S., Festivals of’ in _D.C.A._, together with Duchesne’s _Christian Worship_, E. tr. (pp. 277-281), Wordsworth’s _Ministry of Grace_, and Kellner’s _Heortology_, pp. 301-308. It should be added however with regard to Kellner that the notion that the feast is connected with the Primacy, as distinguished from the Episcopacy of St Peter, seems to be devoid of evidence.
