Bulgarian, 1360. According to ancient practice, monastics recite all 150
psalms on a regular basis. Originally, the
hermits in the desert would recite the entire Psalter every day. With the spread of
cenobitic monasticism, the practice began of chanting the
Canonical Hours in common, and the Psalter thus became the foundation of the
Daily Office, augmented by numerous hymns, prayers and scriptural readings. The custom grew of reciting all 150 psalms each week during the course of the services. To facilitate this, the 150 psalms were divided into 20 sections, called
kathismata (; , meaning literally, "sittings"). Each kathisma is further subdivided into three (), literally, "standings". As indicated by the latter etymology, the ancient practice was to stand while singing the psalms (which was done by all the monks). The word "kathisma" used to refer to the series of hymns sung after a section of the psalter had been read, during the office of
Matins and the original name for these 20 sections was "stichologia". Because the section of the psalter and the hymns sung afterwards are so closely connected, the name for the latter eventually came to be used for the former. Today, the psalms are read, only the reader stands and other people in attendance sit, until the
reader says "Glory to the Father, and to the Son, and to the Holy Spirit..." at which all stand in honor of the
Holy Trinity. This is called a doxology, and is repeated after each stasis, followed by the threefold "Alleluia, alleluia, alleluia, glory to Thee, o God!". The following stasis is introduced by a triple "Kyrie eleison" and a doxology. These may be sung or read, depending on the season. The Orthodox Church uses as its official version of the
Old Testament, the ancient
Septuagint (Greek) as opposed to the more recent
Masoretic (Hebrew)
recension. For this reason, the numbering of the psalms follows the Greek rather than the Hebrew (the
King James Version of the Bible follows the Hebrew numbering). The difference in numbering can be determined from the following table: The divisions of the psalms into kathismata is as follows (using the Septuagint numbering): , 1337. The kathismata are divided up between
Vespers and
Matins, so that all 150 psalms are read during the course of the week. Normally there is one kathisma at Vespers and either two or three at Matins, depending on the day of the week and the time of the year, according to the Church's
liturgical calendar. On Sunday nights and the nights following an
All-Night Vigil, there will be no kathisma at Vespers. During
Great Lent, kathismata are read during the
Little Hours also, so that the entire Psalter is completed twice in a week. Besides the 150 Psalms, the Psalter also contains the nine biblical
Canticles which are chanted at matins alongside the
canon which evolved from them. Kathisma XVII, which is composed entirely of
Psalm 118, "The Psalm of the
Law," is an important component of Matins on Saturdays, some Sundays, Monday-Friday
Midnight office, and at the
funeral service. The entire Book of Psalms is traditionally read aloud or chanted at the side of the deceased during the whole time from death until the funeral, mirroring Jewish tradition, and is a major element of the
wake. When the Psalms are read at a wake, there are special hymns and
litanies for the departed that are chanted between each kathisma, often printed at the end of the Psalter. Some
monasteries have a tradition of a "Cell Rule" whereby each monastic will pray several kathismata a day in addition to the ones that are said publicly during the services. Some Psalters have special hymns and prayers printed between the kathismata to be read as devotions when reciting the Cell Rule. In the 20th century, some lay Christians have adopted a continuous reading of the psalms on weekdays, praying the whole book in four weeks, three times a day, one kathisma a day. In the
East Syriac Rite, the Psalter is divided into similar sections called
hulali. ==Hymns== The word
kathisma initially referred to a set of
troparia (hymns) chanted after each kathisma from the Psalter at Matins, which was when monks would sit down after singing the psalms For the sake of clarity, many translations into English use the term
Sessional Hymns or
Sedalen to indicate these hymns as distinct from the kathisma of psalms they follow. Hymns with the same name are also used after the third ode of the
canon. ==Seating==
