of lectionaries Another project of the Studites' reform was the organisation of the New Testament (Epistle, Gospel) reading cycles, especially its hymns during the period of the triodion (between the pre-Lenten Meatfare Sunday called "Apokreo" and the Holy Week). Older lectionaries had been often completed by the addition of ekphonetic notation and of reading marks which indicate the readers where to start (ἀρχή) and to finish (τέλος) on a certain day. The Studites also created a typikon—a monastic one which regulated the cœnobitic life of the Stoudios Monastery and granted its autonomy in resistance against iconoclast Emperors, but they had also an ambitious liturgical programme. They imported Hagiopolitan customs (of Jerusalem) like the Great Vesper, especially for the movable cycle between Lent and All Saints (triodion and pentekostarion), including a Sunday of Orthodoxy which celebrated the triumph over iconoclasm on the first Sunday of Lent. Unlike the current Orthodox custom Old Testament readings were particular important during Orthros and Hesperinos in Constantinople since the 5th century, while there was no one during the divine liturgy. The Great Vespers according to Studite and post-Studite custom (reserved for just a few feasts like the Sunday of Orthodoxy) were quite ambitious. The evening psalm 140 (kekragarion) was based on simple psalmody, but followed by florid coda of a soloist (monophonaris). A melismatic prokeimenon was sung by him from the ambo, it was followed by three antiphons (Ps 114–116) sung by the choirs, the third used the trisagion or the usual anti-trisagion as a refrain, and an Old Testament reading concluded the prokeimenon. The Hagiopolites treatise The earliest chant manual pretends right at the beginning that John of Damascus was its author. Its first edition was based on a more or less complete version in a 14th-century manuscript, but the treatise was probably created centuries earlier as part of the reform redaction of the tropologia by the end of the 8th century, after Irene's Council of Nikaia had confirmed the octoechos reform of 692 in 787. It fits well to the later focus on Palestine authors in the new chant book heirmologion. Concerning the octoechos, the Hagiopolitan system is characterised as a system of eight diatonic echoi with two additional phthorai (nenano and nana) which were used by John of Damascus and Cosmas, but not by Joseph the Confessor who obviously preferred the diatonic mele of and . It also mentions an alternative system
