The Glagolitic alphabet is believed to have been created by Saints Cyril and Methodius, while the Cyrillic alphabet was invented by the Bulgarian scholar Clement of Ohrid, who was their disciple.

After the war, he played piano and guitar ( his first guitar was built by friend and author Sydney Hopkins, who wrote Mister God, This Is Anna ), and in 1949 joined Chris Barber's Jazz Band where he met blues harmonica player Cyril Davies.

It was used by Saints Cyril and Methodius and their disciples to translate the Bible and other liturgical literature from Greek into Slavic.

In 886 AD, the Bulgarian Empire introduced the Glagolitic alphabet which was devised by the Saints Cyril and Methodius in the 850s.

Writing in 1947, Cyril Garbett comments :" The House of Commons was within its constitutional rights in rejecting in a few hours the work of many anxious years.

Cyril Northcote Parkinson ( 30 July 1909 – 9 March 1993 ) was a British naval historian and author of some sixty books, the most famous of which was his bestseller Parkinson's Law, which led him to be also considered as an important scholar within the field of public administration.

The formal definition of ' two natures ' in Christ was understood by the critics of the council at the time, and is understood by many historians and theologians today, to side with western and Antiochene Christology and to diverge from the teaching of Cyril of Alexandria, who always stressed that Christ is ' one '.

" However, during the reading of Leo's Tome, three passages were challenged as being potentially Nestorian, and their orthodoxy was defended by using the writings of Cyril.

The committee unanimously decided in favor of the orthodoxy of Leo, determining that what he said was compatible with the teaching of Cyril.

A number of other bishops also entered statements to the effect that they believed that Leo's Tome was not in contradiction with the teaching of Cyril as well.

Cyril of Alexandria ( c. 376 – 444 ) was the Patriarch of Alexandria from 412 to 444.

Cyril wrote extensively and was a leading protagonist in the Christological controversies of the later 4th and 5th centuries.

His mother remained close to her brother and under his guidance, Cyril was well educated.

Theophilus died on 15 October 412, and Cyril was made Pope or Patriarch of Alexandria on 18 October 412, against the party favouring Archdeacon Timothy.

On one occasion, Cyril sent the grammaticus Hierax to secretly discover the content of an edict that Orestes was to promulgate on the mimes shows, which attracted great crowds.

When the Jews, with whom Cyril had clashed before, discovered the presence of Hierax, they rioted, complaining that Hierax's presence was aimed at provoking them.

This order had two aims: the first was to quell the riot, the other to mark Orestes ' authority over Cyril.

Orestes was powerless, but nonetheless rejected Cyril's gesture of offering him a Bible, which would mean that the religious authority of Cyril would require Orestes ' acquiescence in the bishop's policy.

However, the Christian population of Alexandria knew that Ammonius had been killed for his assault and not for his faith, and Cyril was obliged to remain silent about the events.

According to lexicographer William Smith, " She was accused of too much familiarity with Orestes, prefect of Alexandria, and the charge spread among the clergy, who took up the notion that she interrupted the friendship of Orestes with their archbishop, Cyril.

Cyril gained an opportunity to restore Alexandria's pre-eminence over both Antioch and Constantinople when an Antiochine priest who was in Constantinople at Nestorius ' behest began to preach against calling Mary the " Mother of God ".

Initially the imperial government ordered both Nestorius and Cyril deposed and exiled.

On August 3, 435, Theodosius II issued an imperial edict that exiled Nestorius to a monastery in the Great Oasis of Hibis ( al-Khargah ), in Egypt, securely within the diocese of Cyril.

In 886 Boris ' governor of Belgrade welcomed the disciples of Saint Cyril and Saint Methodius, who were exiled from Great Moravia into Bulgaria and sent them on to Boris in Pliska.

In the 1860s, a decade and a half after the Brotherhood of Sts Cyril and Methodius was broken up in Kiev, and its founder Nikolay Kostomarov and other prominent figures exiled or arrested, Ukrainian intellectuals were gaining further awareness of their cultural background.

A most notable example of anachronism is the Service of St. Cyril from Skopje ( Скопски миней ), a 13th-century Middle Bulgarian manuscript from northern Macedonia according to which St. Cyril preached with " Bulgarian " books among the Moravian Slavs.

However, the best modern analysis of the sources of the creed ( by A. de Halleux, in Revue Theologique de Louvain 7, 1976 ) and a reading of the acts, or proceedings, of the council ( recently translated into English ) show that the bishops considered Cyril the great authority and that even the language of ' two natures ' derives from him.

About two years after Cyril of Alexandria's death in 444, an aged monk from Constantinople named Eutyches began teaching a subtle variation on the traditional Christology in an attempt ( as he described in a letter to Pope Leo I in 448 ) to stop a new outbreak of Nestorianism.

Cyril is well-known due to his dispute with Nestorius and his supporter Patriarch John of Antioch, whom Cyril excluded from the Council of Ephesus for arriving late.

According to Christian sources, the Jews of Alexandria schemed against the Christians and killed many of them ; Cyril reacted and expelled either all of the Jews, or else only the murderers, from Alexandria, actually exerting a power that belonged to the civil officer, Orestes.

Ephesus was friendly to Cyril, Emperor Theodosius convoked Council of Ephesus ( in 431 ) before Nestorius's supporters from Antioch and Syria had arrived and thus Nestorius refused to attend when summoned.

However, when John of Antioch and the other pro-Nestorius bishops finally reached Ephesus, they assembled their own Council, condemned Cyril for heresy, deposed him from his see, and labelled him as a monster, born and educated for the destruction of the church.

Cyril died about 444, but the controversies were to continue for decades, from the " Robber Synod " of Ephesus ( 449 ) to the Council of Chalcedon ( 451 ) and beyond.

Cyril regarded the embodiment of God in the person of Jesus Christ to be so mystically powerful that it spread out from the body of the God-man into the rest of the race, to reconstitute human nature into a graced and deified condition of the saints, one that promised immortality and transfiguration to believers.

Cyril is portrayed as a fanatic who kills Jews and others who have not converted to Christianity from the traditional religions of antiquity.

Though Longfellow does not accuse Cyril of ordering the death of Hypatia, her work does not shy away from speculating on his part in the murder.

It is believed that Cyril came from a family of Christians and was immediately drawn to the Church.

Separating from his superior, Metropolitan Acacius of Caesarea, a partisan of Arius who taught that Jesus was a divine being created by — and therefore inferior to — God the Father, St. Cyril took the side of the Eusebians of the post-Nicene conciliation party and thus got into difficulties with his superior that were increased by Acacius's jealousy of the importance assigned to St. Cyril's See by the Council of Nicaea.

In 360 this was reversed through the Metropolitan's court influence and Cyril suffered another year's exile from Jerusalem until the Emperor Julian's accession allowed him to return.

Most of the rumors circle from the same source of Saint Jerome who claimed “ Cyril was an out and out Arian, was offered the see on Maximus death on the condition that he would repudiate his ordination at the hands of that Bishop ”.

Cyril was clearly held with high regard by many members of the Church and was able to sustain his place in the History of Jerusalem, despite serious charges and punishments that included banish for years at a time from his position and his city of Jerusalem.
