And this is clear from several Articles of the Statutes, wherein the course of the Ceremonies to be observ’d at the Grand Solemnity are set down; whether observed, on the Eve, the Feast-Day, or the Morrow after: And these three Days together did the Sovereign hold the Grand Feast, whether they personally celebrated the same, or deputed other of the Knights-Companions to that Employment, the cause of the Commissions of Deputation limitting their Power either in general, during the time of the Feast; or in particular, upon the Day of St. George, the Day, and that following, viz. the last Day of the Feast. In like manner, when in succeeding Times, Commissions of Prorogation of the Grand Feast were made use of, we find the three Days continuance of the Feast to be particularly mentioned in the Body of those Commissions: Namely, the Day wherein, by such Appointment, the Feast was to begin, the Grand Day it self, and the Day whereon it ended.

The Directions given in the Statutes, for the Order and Course of this Solemnity, to begin with the Eve, run thus: Every Year upon St. George’s Eve, shall be an Assembly, or Meeting of all the Knights-Companions of the Order, at Windsor Castle, &c. and the same is positively enjoin’d by all the other Bodies of the Statutes.

And as the Grand Feast is generally said to Commence in Vigilia Sancti Georgii, or as it is otherwise exprest in the Black-Book, in Vigilia in future celebratis, or, Vigiliis Divi Georgii, or in Vigilia Festi. So has the time of this preceeding Day several other Denominations given it in the same Register, Vesper ante Diem Sancti Georgii; in Vesperiis Georgianis, in Vesperiis Festi, in Vesperiis Commitionem; and at other times, pridie Divi Georgii, pridie Georgianæ Solemnitatis, pridie Festi, pridie feriarum Divi Georgii, and sometimes per vigilia, and lastly in plain English, St. George’s Eve; all which signify one and the same thing, and are but various Names given to the Evening of the Day foregoing either that of St. George, or that whereon the Grand Feast is appointed to be held by Prorogation.

Thus we see that the Founder began his Solemnity upon the Eve of the Feast Day; which doubtless was in conformity to the Custom of the Church, who made the Vigils and Eves part of the ensuing Festivals, and as Ushers to the Grand Solemnities.

As the Eve was appointed by the Founder for the Commencement of the Anniversary of the Grand Feast, so to make the time more certain, the Statutes express the exact Hour of meeting for beginning the Solemnities, to be at the Hour of Tierce, which in many other Places is called, Hora Tertiarum. But this seemed not sufficient to express clear enough the meaning of a Law, where a Penalty was enjoined, and therefore at a Chapter held at Windsor, 17 Edw. IV. a scruple arising among the Knights-Companions, concerning the Words Hora Tertiarum, whether they were intended to mean three in the Afternoon, or at the Hour of the Church, generally used after Prime Noon before; and fixed it to the latter.

The Registrum Chartaceum Records the same Explanation of the Words; and to let us see that ’twas immediately put in Practice, it is there entered with the Names of those Knights-Companions present with the Sovereign, both in the Morning and Evening of the same Day.

Another Instance of which there is, 3 Hen. VII. on the Eve of the Grand Feast, held by Prorogation at Windsor, where the Sovereign, in regard of the arrival of several Ambassadors, put off the usual Chapter till Noon; whence it is evident, that the Custom at this time was likewise to begin the Solemnity in the Morning.

But notwithstanding the said Decree of King Edw. IV. we find it Anno 11 Hen. VIII. to be meant and intended for three in the Afternoon. And when King Henry VIII. came to Model the Statutes of the Order, in two several Articles, he declares and expounds the Hora Tertia, (which the English Version of those Statutes renders the Hour of Tierce,) to be the Hora Tertia post Merediem, three in the Afternoon; and in another Article of the same Statutes, Hora Tertiarum, id est, Hora Tertiarum post Merediem; and elsewhere, Hora Tertia Vespertina vel Pomeridiana; which Hour, as it was then settled to be the punctual time for the Knights-Companions meeting, to enter on the Solemnity of the Feast, so has it ever since continued unaltered, and usually observed.

The Place of Assembly for the Sovereign and Knights-Companions, hath usually been in such of the Sovereign’s Privy Lodgings, both at Windsor, or elsewhere, as he hath appointed; frequently in the Privy, Withdrawing, or Bed Chambers: To this appointed Place the Knights-Companions repair, to give their Attendance on the Sovereign, having first invested themselves in full Robes, either in their own Lodgings, or some convenient Room at Court, where Garter is to attend them, with notice of the approaching Hour.

The Knights-Companions being come to the Sovereign, as likewise the Officers of the Order, habited in their Mantles, and bearing in their Hands the Symbols of their several Offices, they wait the Sovereign’s being vested in his Robes, till he passes into the Presence Chamber, or give beginning to the Feast, by opening the Chapter at their meeting, before he goes thither.
