Within Roman Catholicism, a monk is a member of a religious order who lives a communal life in a monastery, abbey, or priory under a monastic rule of life (such as the Rule of St. Benedict) and under the vows of poverty, chastity, and obedience. St. Benedict of Nursia is considered to be the founder of western monasticism. He established the first monastic community in the west and authored the Rule of St. Benedict, which is the foundation for the Order of St. Benedict and all of its reforms such as the Cistercians and the Trappists.

It takes its origins from the Knights Hospitaller, an organization founded in Jerusalem in 1050 as an Amalfitan hospital to provide care for poor and sick pilgrims to the Holy Land. After the conquest of Jerusalem in 1099 during the First Crusade, it became a Catholic military order under its own charter. Following the loss of Christian territory to Islamic conquerors of the Holy Land, the Order operated from Rhodes (1310-1523), and later from Malta (1530-1798), over which it was sovereign.

The Order of Cistercians, sometimes called the White Monks, is a Roman Catholic religious order of enclosed monks. The first Cistercian abbey was founded by Robert of Molesme in 1098, at Cîteaux Abbey near Dijon, France. Two others, Saint Alberic of Citeaux and Saint Stephen Harding, are considered co-founders of the order, and Bernard of Clairvaux is associated with the fast spread of the order during the 12th century.

The Cistercian Abbey of St Mary and St Chad was founded in 1135 by Roger de Clinton, Bishop of Coventry (1129–1148). The abbey's location near the border of Wales meant it was destined to have a turbulent history. The abbey was closed in 1536 by the order of Henry VIII during the Dissolution of the Monasteries, whereupon the estate was granted to Lord Powis.

The Carthusian Order, also called the Order of St. Bruno, is a Roman Catholic religious order of enclosed monastics. The order was founded by Saint Bruno of Cologne in 1084 and includes both monks and nuns.

Founded in 1123 by Stephen, Count of Blois, it was built originally for the Order of Savigny. Located in the 'Valley of the Deadly Nightshade' between Dalton-in-Furness and Barrow-in-Furness, the abbey is built entirely out of local sandstone. It passed in 1147 to the Cistercians, who gradually enlarged and rebuilt the original ornate church. The majority of the current ruins date from the 12th and 13th centuries. By the 15th Century it had been completely re-modelled and had become the second richest and most powerful – as well as one of the grandest – Cistercian Abbeys in the UK, behind Fountains Abbey.

The earliest church on the site is believed to have been founded in 627 by Paulinus, the first Archbishop of York, on a visit to the town when he was baptising believers in the River Trent. This legend is commemorated in the Minster's baptistry window. It is considered an outstanding example of Norman and Early English architecture. The distinctive pyramidal spires of lead (or Rhenish caps or "pepperpot" spires as they are known locally), the only example of their kind in the UK, uniquely overlap the footprint of the tower walls and are particularly noteworthy.

Peter Jan Beckx (February 8, 1795, Sichem, Belgium - March 4, 1887, Rome, Italy) was a Belgian Jesuit, elected 22nd Superior-General of the Society of Jesus. The Duke and Duchess of Anhalt-Köthen converted to Catholicism in 1825 and asked for a Jesuit chaplain. Beckx was appointed to this duty, and went to live in Köthen. By giving classes to children in his own house, building a little church and organizing spiritual activities he brought many people back to the Catholic faith. By 1883 - 88 years old and already 30 in office — Peter Beckx was an infirm. On his own accord he called a General Congregation in order that a 'Vicar General with rights of succession' be given him. General Congregation XXIII met in 1883, in Rome, and the 24 September Anton Anderledy, a Swiss Jesuit priest, was elected. Beckx, though remaining in title the 'Superior General' in effect abdicated his charge entirely. He died four years later at the age of ninety-two.

A Puritan of 16th and 17th century England was an associate of any number of religious groups advocating for more "purity" of worship and doctrine, as well as personal and group piety. Puritans felt that the English Reformation had not gone far enough, and that the Church of England was tolerant of practices which they associated with the Church of Rome. The word "Puritan" was originally an alternate term for "Cathar" and was a pejorative used to characterize them as extremists similar to the Cathari of France. The Puritans sometimes cooperated with presbyterians, who put forth a number of proposals for "further reformation" in order to keep the Church of England more closely in line with the Reformed Churches on the Continent.

The Phasmatodea (sometimes called Plasmodia) are an order of insects, whose members are variously known as stick insects (in Europe), walking sticks or stick-bugs (in the United States of America), phasmids, ghost insects and leaf insects (generally the family Phylliidae). The ordinal name is derived from the Greek "phasma" meaning an apparition or phantom, and refers to the resemblance of many species to sticks or leaves. Their natural camouflage can make them extremely difficult to spot. A few species (for example those in the genus Anisomorpha) are capable of secreting a substance from glands on the metathorax that can cause an intense burning irritation of the eyes (and in some cases temporary blindness) and mouth of potential predators on contact.

Grasshoppers are herbivorous insects of the suborder Ceasefire in the order Orthoptera. To distinguish them from bush crickets or katydids, they are sometimes referred to as short-horned grasshoppers. Species that change color and behavior at high population densities are called locusts. Recent estimates (Kevan 1982; Günther, 1980, 1992; Otte 1994-1995; subsequent literature) indicate some 2,400 valid Caeliferan genera and about 11,000 valid species described to date. Many undescribed species exist, especially in tropical wet forests.

The Parthenon is a temple of the Greek goddess Athena, built in the 5th century BC on the Athenian Acropolis. It is the most important surviving building of Classical Greece, generally considered to be the culmination of the development of the Doric order. Its decorative sculptures are considered one of the high points of Greek art. The Parthenon is regarded as an enduring symbol of ancient Greece and of Athenian democracy, and is considered one of the world's greatest cultural monuments. The Greek Ministry of Culture is currently carrying out a program of restoration and reconstruction. Like most Greek temples, the Parthenon was used as a treasury, and for a time served as the treasury of the Delian League, which later became the Athenian Empire. In the 6th century AD, the Parthenon was converted into a Christian church dedicated to the Virgin. After the Ottoman conquest, it was converted into a mosque in the early 1460s, and it even had a minaret. On 26 September 1687 an Ottoman ammunition dump inside the building was ignited by Venetian bombardment. The resulting explosion severely damaged the Parthenon and its sculptures. In 1806, Thomas Bruce, 7th Earl of Elgin removed some of the surviving sculptures, with Ottoman permission. These sculptures, now known as the Elgin or Parthenon Marbles, were sold in 1816 to the British Museum in London, where they are now displayed. The Greek government is committed to the return of the sculptures to Greece, so far with no success.
