Incipit in the context of "Book of Lamentations"

The Epic of Gilgamesh (/ˈɡɪlɡəmɛʃ/) is an epic from ancient Mesopotamia. The literary history of Gilgamesh begins with five Sumerian poems about Gilgamesh (formerly read as Sumerian "Bilgames"), king of Uruk, some of which may date back to the Third Dynasty of Ur (c. 2100 BCE). These independent stories were later used as source material for a combined epic in Akkadian. The first surviving version of this combined epic, known as the "Old Babylonian" version, dates back to the 18th century BCE and is titled after its incipit, Shūtur eli sharrī ("Surpassing All Other Kings"). Only a few tablets of it have survived. The later Standard Babylonian version compiled by Sîn-lēqi-unninni dates to somewhere between the 13th to the 10th centuries BCE and bears the incipit Sha naqba īmuru ("He Who Saw the Deep(s)", lit. "He Who Sees the Unknown"). Approximately two-thirds of this longer, twelve-tablet version have been recovered. Some of the best copies were discovered in the library ruins of the 7th-century BCE Assyrian King Ashurbanipal.

The first part of the story discusses Gilgamesh (who was king of Uruk) and Enkidu, a wild man created by the gods to stop Gilgamesh from oppressing the people of Uruk. After Enkidu becomes civilized through sexual initiation with Shamhat, he travels to Uruk, where he challenges Gilgamesh to a test of strength. Gilgamesh wins the contest; nonetheless, the two become friends. Together they make a six-day journey to the legendary Cedar Forest, where they ultimately slay its Guardian, Humbaba, and cut down the sacred Cedar. The goddess Ishtar sends the Bull of Heaven to punish Gilgamesh for spurning her advances. Gilgamesh and Enkidu kill the Bull of Heaven, insulting Ishtar in the process, after which the gods decide to sentence Enkidu to death and kill him by giving him a fatal illness.

The Book of Revelation, also known as the Book of the Apocalypse or the Apocalypse of John, is canonically the last book of the New Testament. Written in Greek, its title is derived from the first word of the text, apocalypse (Koine Greek: ἀποκάλυψις, romanized: apokálypsis), which means "revelation" or "unveiling". The Book of Revelation is the only apocalyptic book in the New Testament canon, and occupies a central place in Christian eschatology.

The book spans three literary genres: the epistolary, the apocalyptic, and the prophetic. It begins with John, on the island of Patmos in the Aegean Sea, addressing letters to the "Seven Churches of Asia" with exhortations from Christ. He then describes a series of prophetic and symbolic visions, which would culminate in the Second Coming of Jesus Christ. These visions include figures such as a Woman clothed with the sun with the moon under her feet and a crown of twelve stars, the Serpent, the Seven-Headed Dragon, and the Beast.

Gregorian chant is the central tradition of Western plainchant, a form of monophonic, unaccompanied sacred song in Latin (and occasionally Greek) of the Roman Catholic Church. Gregorian chant developed mainly in western and central Europe during the 9th and 10th centuries, with later additions and redactions. Although popular legend credits Pope Gregory I with inventing Gregorian chant, scholars believe that he only ordered a compilation of melodies throughout the whole Christian world, after having instructed his emissaries in the Schola Cantorum, where the neumatical notation was perfected, with the result of most of those melodies being a later Carolingian synthesis of the Old Roman chant and Gallican chant.

Gregorian chants were organized initially into four, then eight, and finally 12 modes. Typical melodic features include a characteristic ambitus, and also characteristic intervallic patterns relative to a referential mode final, incipits and cadences, the use of reciting tones at a particular distance from the final, around which the other notes of the melody revolve, and a vocabulary of musical motifs woven together through a process called centonization to create families of related chants. The scale patterns are organized against a background pattern formed of conjunct and disjunct tetrachords, producing a larger pitch system called the gamut. The chants can be sung by using six-note patterns called hexachords. Gregorian melodies are traditionally written using neumes, an early form of musical notation from which the modern four-line and five-line staff developed. Multi-voice elaborations of Gregorian chant, known as organum, were an early stage in the development of Western polyphony.

Sîn-lēqi-unninni (Akkadian: 𒁹𒀭𒌍𒋾𒀀𒅆 30-TI-ER₂) was a mašmaššu who lived in Mesopotamia, probably in the period between 1300 BC and 1000 BC. He is traditionally thought to have compiled the best-preserved version of the Epic of Gilgamesh. His name is listed in the text itself, which was unorthodox for works written in cuneiform. His version is known by its incipit, or first line "ša nagba īmuru" ("He who saw the deep" or "The one who saw the Abyss"). The extent to which his version is different from earlier texts is unknown; Andrew R. George argues that Sîn-lēqi-unninni "gave [The Epic of Gilgamesh] its final, fixed form". Tigay acknowledges that Sîn-lēqi-unninni shifted "Gilgamesh's greatness from deeds to the acquisition of knowledge". At time it was also known as "Gilgamesh series" (iškar Gilgāmeš).

The prologue features the only instance of first person narration by Sîn-lēqi-unninni. His version includes Utnapishtim's story of the Flood in tablet XI and, in tablet XII, the Sumerian Gilgamesh, Enkidu, and the Netherworld.

Quo Primum Tempore (English: From the beginning whence) is the incipit of an Apostolic Constitution in the form of a Papal bull issued by Pope Pius V on 14 July 1570. This Pontifical decree promulgated the Roman Missal and made its use obligatory throughout the Latin Church of the Catholic Church, except where there existed a different Catholic Mass liturgy of the Latin Church of at least two hundred years prior and standing.

The Book of Genesis (from Greek Γένεσις, Génesis; Biblical Hebrew: בְּרֵאשִׁית‎, romanized: Bərēʾšīṯ, lit. 'In [the] beginning'; Latin: Liber Genesis) is the first book of the Hebrew Bible and the Christian Old Testament. Its Hebrew name is the same as its first word, bereshit ('in the beginning'). The primary narrative of Genesis includes a legendary account of the creation of the world, the early history of humanity, and the origins of the Jewish people. In Judaism, the theological importance of Genesis centers on the covenants linking God to his chosen people and the people to the Promised Land.

Genesis is part of the Torah or Pentateuch, the first five books of the Bible. Tradition credits Moses as the Torah's author. However, there is scholarly consensus that the Book of Genesis was composed several centuries later, after the Babylonian captivity, possibly in the fifth century BCE. Based on the scientific interpretation of archaeological, genetic, and linguistic evidence, mainstream biblical scholars consider Genesis to be primarily mythological rather than historical.

The Athanasian Creed—also called the Quicunque Vult (or Quicumque Vult), which is both its Latin name and its opening words, meaning "Whosoever wishes"—is a Christian statement of belief focused on Trinitarian doctrine and Christology. Used by Christian churches since the early sixth century, it was the first creed to explicitly state the equality of the three hypostases of the Trinity. It differs from the Nicene-Constantinopolitan Creed and the Apostles' Creed in that it includes anathemas condemning those who disagree with its statements, as does the original Nicene Creed.

Widely accepted in Western Christianity, including by the Roman Catholic Church, Lutheran Churches (it is part of the Lutheran confessions set out in the Book of Concord), Anglican Churches, Reformed Churches, and ancient liturgical churches, the Athanasian Creed has been used in public worship less frequently, with exception of Trinity Sunday. However, part of it can be found as an "Authorized Affirmation of Faith" in the main volume of the Common Worship liturgy of the Church of England published in 2000. Despite falling out of liturgical use, the creed's influence on current Protestant understanding of trinitarian doctrine is clear.

The Lord's Prayer, also known by its incipit Our Father (Greek: Πάτερ ἡμῶν, Latin: Pater Noster), is a central Christian prayer attributed to Jesus. It contains petitions to God focused on God's holiness, will, and kingdom, as well as human needs, with variations across manuscripts and Christian traditions.

Two versions of this prayer are recorded in the gospels: a longer form within the Sermon on the Mount in the Gospel of Matthew, and a shorter form in the Gospel of Luke when "one of his disciples said to him, 'Lord, teach us to pray, as John taught his disciples.'" Scholars generally agree that the differences between the Matthaean and Lucan versions of the Lord's Prayer reflect independent developments from a common source. The first-century text Didache (at chapter VIII) reports a version closely resembling that of Matthew and the modern prayer. It ends with the Minor Doxology.

Psalm 137 is the 137th psalm of the Book of Psalms, beginning in English in the King James Version: "By the rivers of Babylon, there we sat down". The Book of Psalms is part of the third section of the Hebrew Bible, and a book of the Christian Old Testament. In the slightly different numbering system used in the Greek Septuagint and Latin Vulgate translations of the Bible, this psalm is Psalm 136. In Latin, it is known by the incipit, "Super flumina Babylonis". The psalm is a communal lament about remembering Zion, and yearning for Jerusalem while dwelling in exile during the Babylonian captivity.

The psalm forms a regular part of liturgy in Jewish, Eastern Orthodox, Catholic, Lutheran, Anglican and other Protestant traditions. It has often been set to music and paraphrased in hymns.
