[Footnote 69: The Lord's Prayer consists of half a dozen lines;
the Sacramentarius and Antiphonarius of Gregory fill 880 folio
pages, (tom. iii. p. i. p. 1 - 880;) yet these only constitute a
part of the Ordo Romanus, which Mabillon has illustrated and
Fleury has abridged, (Hist. Eccles. tom. viii. p. 139 - 152.)]
