In this component, the reader learns the deeds of the Holy Spirit. Similar to the Hours of the Holy Cross, within each hour there is a hymn with an account. Matins tells of the Holy Spirit becoming flesh within the Virgin Mary. The sequence continues as follows: rising after death and showing himself to the disciples; the Descent of the Holy Spirit at Pentecost; giving the disciples the ability to understand and speak all languages; the graces of the Holy Spirit; the Holy Spirit shall defend; the Holy Spirit as comforter. Each hour asks for the Holy Spirit to infuse the reader.

Similar to the Hours of the Cross, it is common to adorn only matins. In this section, the most common image is the Descent of the Holy Ghost at Pentecost. This image depicts the Holy Ghost visiting the assembled disciples, giving them the ability to speak in many different languages as the Holy Spirit filled them.

Early depictions have the Virgin Mary centered and flanked by the Apostles, with the dove of the Holy Ghost descending among them. Tongues of fire appear above their heads. Byzantine representations sometimes combine the Ascension with Pentecost. As such, Mary stands among the Apostles. Christ in a mandorla is raised by Angels. The flaming tongues, as well as Mary, may or may not be depicted. Pentecost is seen with the hetoimasia (Christ’s empty throne in preparation for the Last Judgement), with the Twelve Apostles being grouped around the throne, from which rays of light descend upon them.
