Keystone (architecture)
A keystone (or capstone) is the wedge-shaped stone at the apex of a masonry arch or typically round-shaped one at the apex of a vault. In both cases it is the final piece placed during construction and locks all the stones into position, allowing the arch or vault to bear weight. In arches and vaults (such as quasi-domes) keystones are often enlarged beyond the structural requirements and decorated. A variant in domes and crowning vaults is a lantern. Keystones, as a hallmark of strength or good architecture, or their suggested form are sometimes placed in the centre of the flat top of doors, recesses and windows for decorative effect, so as to form an upward projection of a lintel. Although a masonry arch or vault cannot be self-supporting until the keystone is placed, the keystone experiences the least stress of any of the voussoirs, due to its position at the apex. Old keystones can decay due to vibration, a condition known as bald arch. Architecture In a rib-vaulted ...

Order Of Mark Master Masons
The Order of Mark Master Masons is an appendant order of Freemasonry that exists in some Masonic jurisdictions, and confers the degrees of ''Mark Mason'' and ''Mark Master''. Purpose Similarly to Craft Freemasonry, Mark Masonry conveys moral and ethical lessons using a ritualised allegory based around the building of King Solomon's Temple. The ceremonies of Mark Masonry require the candidate to undertake the role of a Fellowcraft, thus the degree is seen as an extension of the Fellowcraft Degree, and the philosophical lessons conveyed are appropriate to that stage in a candidate's Masonic development. While the Fellowcraft degree teaches a Mason what the historical wages of a Fellowcraft Mason are, the Mark Master Mason degree teaches a Mason how to earn those wages, how to prove his work is his own, and what the penalty for fraud was during the building of the Temple. The legend reconciles the Anglo-American version of the Hiramic legend with the 3,300 Master Masons of Ander ...

Boss (architecture)
In architecture, a boss is a knob or protrusion of wood, stone, or metal. Description Bosses can often be found in the ceilings of buildings, particularly at the keystones at the intersections of a rib vault. In Gothic architecture, such roof bosses (or ceiling bosses) are often intricately carved with foliage, heraldic devices or other decorations. Many feature animals, birds, or human figures or faces, sometimes realistic, but often Grotesque: the Green Man is a frequent subject. The Romanesque Norwich Cathedral in Norfolk, England, has the largest number of painted carved stone bosses in the world; an extensive and varied collection of over one thousand individual pieces. Many of these decorated bosses still bear the original gilt and pigments from the time of their creation. A different sense of boss was also an important feature of ancient and Classical construction. When stone components were rough-cut offsite at quarries, they were usually left with bosses (sma ...

Jesus Christ
Jesus, likely from he, יֵשׁוּעַ, translit=Yēšūaʿ, label=Hebrew/Aramaic ( AD 30 or 33), also referred to as Jesus Christ or Jesus of Nazareth (among other names and titles), was a first-century Jewish preacher and religious leader; he is the central figure of Christianity, the world's largest religion. Most Christians believe he is the incarnation of God the Son and the awaited Messiah (the Christ) prophesied in the Hebrew Bible. Virtually all modern scholars of antiquity agree that Jesus existed historically. Research into the historical Jesus has yielded some uncertainty on the historical reliability of the Gospels and on how closely the Jesus portrayed in the New Testament reflects the historical Jesus, as the only detailed records of Jesus' life are contained in the Gospels. Jesus was a Galilean Jew who was circumcised, was baptized by John the Baptist, began his own ministry and was often referred to as "rabbi". Jesus debated with fellow Jews on ...
