Cosmas of Maiuma was a highly influential bishop and hymnographer in the Eastern Christian tradition.

He is often identified by several names, including Cosmas Hagiopolites, which means "of the Holy City." Other titles include Cosmas of Jerusalem, Cosmas the Melodist, or Cosmas the Poet. He served as a religious leader and a master of sacred song. Both the Eastern Orthodox and the Catholic Churches venerate him as a saint. In the Eastern Orthodox Church, he is held in high regard as "the glory of the Church" and "a vessel of divine grace."

His life followed a path from Damascus to the monastic centers near Jerusalem. Cosmas was born in Damascus, located in modern-day Syria. He was an orphan at a young age and was adopted by a man named Sergius. This adoption made him the foster-brother of John of Damascus, another very important religious figure. The two boys were educated by an elderly monk from Calabria named Cosmas. This teacher was known as "Cosmas the Monk" to avoid confusion with his student. Eventually, both Cosmas and John moved to Jerusalem to become monks. They lived in a lavra-type monastery belonging to Sabbas the Sanctified.

As a hymnographer, Cosmas helped shape the musical traditions of the Byzantine era. He is considered one of the best representatives of later Greek classical hymnography. This style is characterized by artistic liturgical chants known as canons. Cosmas worked alongside John of Damascus to develop the Octoechos. The Octoechos is a musical system used to organize liturgical chants.

Cosmas also wrote scholia, which are detailed commentaries, on the poems of Gregory of Nazianzus. These writings show his skill as a learned prose author and a poet.

Cosmas composed several specific types of religious music for different parts of the church year. He wrote solemn canons for the Matins of Lazarus Saturday and Palm Sunday. He also composed the Triodes, which are canons containing only three Canticles. These are chanted during the period known as Holy Week. His work includes the first canon of the Nativity, which was based on a sermon by Gregory the Theologian. He is particularly famous for his "Canon for Christmas Day." In total, the liturgical books of the Orthodox Church attribute fourteen canons to him.

One of his most enduring musical contributions is the piece starting with "More honourable than the cherubim."

This composition is included in the Axion Estin. It is sung regularly during Matins, the Divine Liturgy, and other church services. While these hymns were originally created for the Church of Jerusalem, they became universal. This spread happened because of the influence of Constantinople.

However, historians note a complication regarding his authorship. Because his teacher was also named Cosmas and was a hymn writer, it is not certain if every hymn attributed to him was actually his work.

The exact dates of Cosmas's life are a subject of historical discussion. Some sources place his birth around 675 and his death around 751. Other records suggest he died in 773 or even 794. During his life, he helped defend the Church against the heresy of iconoclasm. In 743, he left the monastery when he was appointed Bishop of Maiuma. Maiuma was the port city of ancient Gaza. He lived to a great old age, outliving his foster-brother John by many years.

Religious communities continue to honor his memory through specific feast days. The Eastern Orthodox Church observes his feast on October 12 according to the Julian Calendar. On the Gregorian Calendar, this date is October 25. The Greek Church observes his feast on October 14 in the Julian Calendar, which is October 27 in the Gregorian system. His works are preserved in various large collections. These include the Patrologia Graecae and the Anthologia graeca carminum christianorum. His legacy remains a central part of Eastern Christian liturgical life.
