Feast day in the context of Feast of Fools

In the practice of religion, a cult image is a human-made object that is venerated or worshipped for the deity, spirit or daemon that it embodies or represents. In several traditions, including the ancient religions of Egypt, Greece and Rome, and Hinduism, cult images in a temple may undergo a daily routine of being washed, dressed, and having food left for them. Processions outside the temple on special feast days are often a feature. Religious images cover a wider range of all types of images made with a religious purpose, subject, or connection. In many contexts "cult image" specifically means the most important image in a temple, kept in an inner space, as opposed to what may be many other images decorating the temple.

The term idol is an image or representation of a god used as an object of worship, while idolatry is the worship of an "idol" as though it were God.

Mark the Evangelist (Koinē Greek: Μᾶρκος, romanized: Mârkos), also known as John Mark (Koinē Greek: Ἰωάννης Μᾶρκος, romanized: Iōánnēs Mârkos; Aramaic: ܝܘܚܢܢ, romanized: Yōḥannān) or Saint Mark, was an Egyptian who is traditionally ascribed to be the author of the Gospel of Mark. Most modern scholars agree that the gospel of Mark is anonymous, though the topic remains contentious among experts. Scholarship is inconclusive on authorship; some reject the attribution to Mark while others debate the identity of Mark. According to Church tradition, Mark founded the episcopal see of Alexandria, which was one of the five most important sees of early Christianity. His feast day is celebrated on April 25, and his symbol is the winged lion.

The liturgical year, also called the church year, Christian year, ecclesiastical calendar, or kalendar, consists of the cycle of liturgical days and seasons that determines when feast days, including celebrations of saints, are to be observed, and which portions of scripture are to be read.

Distinct liturgical colours may be used in connection with different seasons of the liturgical year. The dates of the festivals vary somewhat among the different churches, although the sequence and logic is largely the same.

An altarpiece is a painting or sculpture, including relief, of religious subject matter made for placing at the back of or behind the altar of a Christian church. Though most commonly used for a single work of art such as a painting or sculpture, or a set of them, the word can also be used of the whole ensemble behind an altar, otherwise known as a reredos, including what is often an elaborate frame for the central image or images. Altarpieces were one of the most important products of Christian art especially from the late Middle Ages to the era of Baroque painting.

The word altarpiece, used for paintings, usually means a framed work of panel painting on wood, or later on canvas. In the Middle Ages they were generally the largest genre for these formats. Murals in fresco tend to cover larger surfaces. The largest painted altarpieces developed complicated structures, especially winged altarpieces with hinged side wings that folded in to cover the main image, and were painted on the reverse with different simpler images. Often this was the normal view shown in the church, except for Sundays and feast days, when the wings were opened to display the main image. At other times visitors could usually see this by paying the sacristan.

According to the canonical Gospels, Joseph was a 1st-century Jewish man of Nazareth who was married to Mary, the mother of Jesus, and was the legal father of Jesus.

Joseph is venerated as Saint Joseph in the Catholic Church, Eastern Orthodox Church, Oriental Orthodox Church, Anglicanism and Lutheranism. In Catholic traditions, Joseph is regarded as the patron saint of workers and is associated with various feast days. The month of March is dedicated to Saint Joseph. Pope Pius IX declared him to be both the patron and the protector of the Catholic Church, in addition to his patronages of the sick and of a holy death, due to the belief that he died in the presence of Jesus and Mary. Joseph has become patron of various dioceses and places. Being a patron saint of virgins, he is venerated as "most chaste". The veneration of the pure and most Chaste Heart of Joseph has, in contrast to the Most Sacred Heart of Jesus and the Immaculate Heart of Mary, no liturgical cultus, but is a private devotion.

The term idol, usually pejorative in English (except in Indian English where it usually carries no hostile implication), is an image or representation of a god used as an object of worship, while idolatry is the worship of an "idol" as though it were God. Anthropologists reporting on many cultures are generally sceptical that images themselves are in fact regarded as deities within religions, rather than representations of deities; this, however, has been since antiquity the recurrent charge of those opposed to religious images.

Pope Leo IX (Italian: Leone IX, German: Leo IX., 21 June 1002 – 19 April 1054), born Bruno von Egisheim-Dagsburg, was the head of the Catholic Church and ruler of the Papal States from 12 February 1049 to his death in 1054. Leo IX is considered to be one of the most historically significant popes of the Middle Ages; he was instrumental in the precipitation of the Great Schism of 1054, considered the turning point in which the Catholic and Eastern Orthodox Churches formally separated.

Leo IX favoured traditional morality in his reformation of the Catholic Church. One of his first public acts was to hold the Easter synod of 1049; he joined Emperor Henry III in Saxony and accompanied him to Cologne and Aachen. He also summoned a meeting of the higher clergy in Reims, in which several important reforming decrees were passed. At Mainz, he held a council at which the Italian and French as well as the German clergy were represented, and ambassadors of the Byzantine emperor were present. Here too, simony and clerical marriage were the principal matters dealt with. He is regarded as a saint by the Catholic Church; his feast day is celebrated on 19 April.

A patronal feast or patronal festival (Spanish: fiesta patronal; Catalan: festa patronal; Portuguese: festa patronal; Italian: festa patronale; French: fête patronale) is a yearly celebration dedicated – in countries influenced by Christianity – to the 'heavenly advocate' or 'patron' of the location holding the festival, who is a saint or virgin. The day of this celebration is called patronal feast day, patronal day or patron day of said location.

Patronal festivals may reflect national holidays (e.g. the feast of Saint George, patron saint of England, Georgia, Bulgaria, Romania, Portugal, and various regions of Spain), but they usually reflect the celebration of a single city or town.In larger cities, there may even be several festivals, usually about the patron saint of the local parish.

David I or Dauíd mac Maíl Choluim (Modern Gaelic: Daibhidh I mac [Mhaoil] Chaluim; c. 1084 – 24 May 1153) was a 12th century ruler and saint who was Prince of the Cumbrians from 1113 to 1124 and King of Scotland from 1124 to 1153. The youngest son of King Malcolm III and Queen Margaret, David spent most of his childhood in Scotland but was exiled to England temporarily in 1093. Perhaps after 1100, he became a dependent at the court of King Henry I of England, by whom he was influenced.

When David's brother Alexander I died in 1124, David chose, with the backing of Henry I, to take the Kingdom of Alba (Scotland) for himself. He was forced to engage in warfare against his rival and nephew, Máel Coluim mac Alaxandair. Subduing the latter seems to have taken David ten years, a struggle that involved the destruction of Óengus, Mormaer of Moray. David's victory allowed the expansion of control over more distant regions, theoretically part of his Kingdom. After the death of his former patron Henry I, David supported the claims of Henry's daughter and his own niece, Empress Matilda, to the throne of England. In the process, he came into conflict with King Stephen and was able to expand his power in northern England, despite his defeat at the Battle of the Standard in 1138. David I is a saint of the Catholic Church, with his feast day celebrated on 24 May.

Theophanes the Confessor (Greek: Θεοφάνης Ὁμολογητής) or Theophanes of the Great Field (Greek: Θεοφάνης τοῦ Μεγάλου Ἄγρου; c. 759 – 817 or 818) was a member of the Byzantine aristocracy who became a monk and chronicler. He served in the court of Emperor Leo IV the Khazar before taking up the religious life. Theophanes attended the Second Council of Nicaea in 787 and resisted the iconoclasm of Leo V the Armenian, for which he was imprisoned. He died shortly after his release.

Theophanes the Confessor, venerated on 12 March in both the Catholic Church and the Eastern Orthodox Church, should not be confused with Theophanes of Nicaea, whose feast is commemorated on 11 October.

Cunigunde of Luxembourg, OSB (German: Kunigunde) (c. 975 – 3 March 1040), also called Cunegundes, Cunegunda, and Cunegonda and, in Latin, Cunegundis or Kinigundis, was Empress of the Holy Roman Empire by marriage to Holy Roman Emperor Henry II. She ruled as interim regent after the death of her spouse in 1024. She is a saint and the patroness of Luxembourg; her feast day is 3 March.

Saint George (Ancient Greek: Γεώργιος, romanized: Geṓrgios; died 23 April 303), also George of Lydda, was an early Christian martyr, born in Cappadocia in Anatolia, who is venerated as a saint in Christianity. According to holy tradition, he was a soldier in the Roman army. Saint George’s mother Saint Polychronia is believed to have come from Syria Palaestina and his father Saint Gerontios is believed to be of Syrian Cappadocian origin. He became a member of the Praetorian Guard for Roman emperor Diocletian, but was executed as part of the Diocletianic persecution. He is one of the most venerated saints, heroes, and megalomartyrs in Christianity, and he has been especially venerated as a military saint since the Crusades. He is also prominently venerated by the Druze, and by some Muslim groups, as a martyr of monotheistic faith.

In hagiography, he is immortalised in the legend of Saint George and the Dragon and as one of the most prominent military saints. In Roman Catholicism, he is also venerated as one of the Fourteen Holy Helpers. His feast day, Saint George's Day, is traditionally celebrated on 23 April. Historically, the countries of Portugal, England, Bosnia and Herzegovina, Bulgaria, Georgia, Ukraine, Malta, Ethiopia, the regions of Catalonia and Aragon, and the cities of Moscow and Beirut have claimed George as their patron saint, as have several other regions, cities, universities, professions, and organizations. The Church of Saint George in Lydda, now Lod in Israel, has a sarcophagus traditionally believed to contain St. George's relics.

In Christianity, the Biblical Magi (/ˈmeɪdʒaɪ/ MAY-jy or /ˈmædʒaɪ/ MAJ-eye; singular: magus), also known as the Three Wise Men, Three Kings, and Three Magi, are distinguished foreigners who visit Jesus after his birth, bearing gifts of gold, frankincense, and myrrh in homage to him. In Western Christianity, they are commemorated on the feast day of Epiphany—sometimes called "Three Kings Day"—and commonly appear in the nativity celebrations of Christmas. In Eastern Christianity, they are commemorated on Christmas day.

The Magi appear solely in the Gospel of Matthew, which states that they came "from the east" (Greek: ἀπὸ ἀνατολῶν, romanized: apo anatolōn) to worship the "one who has been born king of the Jews". Their names, origins, appearances, and exact number are unmentioned and derive from the inferences or traditions of later Christians. In Western Christianity and Eastern Orthodox Christianity, they are usually assumed to have been three in number, corresponding with each gift; in Syriac Christianity, they often number twelve. Likewise, the Magi's social status is never stated: although some biblical translations describe them as astrologers, they were increasingly identified as kings by at least the third century, which conformed with Christian interpretations of Old Testament prophecies that the messiah would be worshipped by kings.

In the liturgical calendar of the Roman Rite, a solemnity is a feast day of the highest rank celebrating a mystery of faith such as the Trinity, an event in the life of Jesus, his mother Mary, his legal father Joseph, or another important saint. The observance begins with the vigil on the evening before the actual date of the feast. Unlike feast days of the rank of feast (other than feasts of the Lord) or those of the rank of memorial, solemnities replace the celebration of Sundays outside Advent, Lent, and Easter (those in Ordinary Time).

The word comes from postclassical Latin sollemnitas, meaning a solemnity, festival, celebration of a day.

A katholikon or catholicon (Greek: καθολικόν) or sobor (Church Slavonic: съборъ) refers to one of three things in the Eastern Orthodox Church:

• The cathedral of a diocese.
• The major church building (temple) of a monastery corresponding to a conventual church in Western Christianity.
• A large church in a city at which all the faithful of the city gather to celebrate certain important feasts rather than go to their local parish church.

The name derives from the fact that it is typically the largest church where all gather together to celebrate the major feast days of the liturgical year. In Russia, it is common for a katholikon to have a smaller church in the basement which can be more easily heated in the winter. A katholikon may have special architectural features in it, such as a cathedra (episcopal throne), or both an esonarthex (inner-narthex) and exonarthex (outer narthex), used for special services such as the Paschal vigil or a lity.

Ivo of Kermartin, TOSF (17 October 1253 – 19 May 1303), also known as Yvo, Yves, or Ives (and in Breton as Erwan, Iwan, Youenn or Eozenn, depending on the region, and known as Yves Hélory (also Helori or Heloury) in French), was a parish priest among the poor of Louannec, the only one of his station to be canonized in the Middle Ages. He is the patron of Brittany, lawyers, and abandoned children. His feast day is 19 May. Poetically, he is referred to as "advocate of the poor".

Unity Day, also called the National Unity Day (Russian: День народного единства, romanized: Denʹ narodnogo yedinstva) and the Day of People's Unity, is a national holiday in Russia held on 4 November [O.S. 22 October]. It commemorates the popular uprising which ended the Polish-Lithuanian occupation of Moscow in November 1612, and more generally the end of the Time of Troubles and turning point of the Polish intervention in Russia.

The day's name alludes to the idea that all classes of Russian society united to preserve Russian statehood when there was neither a tsar nor a patriarch to guide them. In 1613 tsar Mikhail Romanov instituted a holiday named Day of Moscow’s Liberation from Polish Invaders. It was celebrated in the Russian Empire until 1917, when it was replaced with October Revolution Day, a commemoration of the Russian Revolution. Unity Day was reinstituted by the Russian Federation in 2005, when the events of the year 1612 have been celebrated instead of those of 1917 every 4 November since. The day is also the feast day of the Russian Orthodox icon of Our Lady of Kazan.
