Pannyhis Şi Orthros: Formularul Liturgic Cu „aliluia” Şi Pomenirea Morţilor În Perioada Octoihului

Pannychis and Orthros: The Liturgical Formulary with "Alleluia" and The Commemoration of the Deceased During The Time of The Octoechos.During the liturgical week, Saturdays have an intermediate place between weekdays (Monday-Friday) and Sundays.The liturgical theme of the Saturday celebrations is double: the commemoration of all Saints and all the departed, with the focus on one theme or the other.This specific situation lead to the existence of two different liturgical structures for a Saturday celebration.The first, resembling the usual weekday orderduring which at Matins is sungThe Lord is God… -, is frequently used; the secondduring which at Matins is sung Alleluia -, has become almost obsolete, probably as a consequence of the difficulties related to its celebration.The present study intends to present an algorithm which allows the identifications of the liturgical days when Alleluia services might be celebrated, to perform a brief analysis of the structure of these celebrations, and to identify the system according to which hymns are distributed across these liturgical celebrations.
