ith the rite of a simple office.
The rubrics of the New Psalter (Title I., sec. 6) direct, "_In officio
Sanctae Mariae in Sabbato et in festis simplicibus sic officium
persolvendum est; ad matutinum, Invitatorium et hymnus dicuntur de eodem
officio vel de iisdem Festis; Psalmi cum suis antiphonis et versu de
Feria occurente I. et II. Lectis de Feria cum Responsoriis Propriis vel
de Communi. III. vero lectio de officio vel Festo duabus lectionibus in
unum junctis si quando duae pro Festo habeatur, ad reliquas autem Horas
omnia dicuntur, prouti supra num. 5 in Festis Duplicibus expositum est_."
In the Office of the Blessed Virgin for Saturdays (Decree S.C.R., 26th
January. 1916) the antiphons and Psalms at Matins, Lauds and small Hours
are to be said from the Saturday and from the _capitulum_ onwards all is
to be taken from the office of the Blessed Virgin.

This office is not to be confounded with the _officium parvum Beatae
Mariae._ The office _de Sabbato_ is obligatory throughout the Church.
The _officium parvum_ was only for choir use, an addition to the office
of the day. Saturday, dedicated to the Blessed Virgin, is of great
antiquity, as the mention of it in the works of St. Peter Damien, St.
Bernard and Pope Benedict XIII. shows, but as to the time of its origin
or a history of its growth, little seems to be known. At first the cult
consisted in various and voluntary prayers and practices. About the
middle of the fourteenth century an office was composed for recital on
Saturdays as dedicated to the Mother of God. The office in our
Breviaries was composed by St. Pius V, (1566-1572).

TITLE IX,--COMMEMORATIONS.

The rules laid down in the general rubrics of the Breviary for
commemorations were never very simple, and when we read the changes
brought about in _De ratione Divini officii recitandi juxta novum
Psalteri ordinem_, Titles II., III., IV., V., VI., with' the decrees of
the Congregation (January, 1912), and subsequently (_Abhinc duos Annos_)
everyone must fear to tread the maze with certainty and must often fall
back gratefully on the labours of the compilers of the _Ordo_ which he
follows. Or, perhaps, doubts may be dispelled by _The New Psalter_
(Burton and Myers) published in 1912. The chapter on the Calendar in
that book is worth study, but needs now additions and corrections, owing
to the issue of more recent decrees.

In the study of commemorations and translations of feasts there are two
