Also found in: Dictionary, Thesaurus.
ceramic structural material that, in modern times, is made by pressing clay into blocks and firing them to the requisite hardness in a kiln. Bricks in their most primitive form were not fired but were hardened by being dried in the sun.

structural masonry material made by mixing broken stone or gravel with sand, cement, and water and allowing the mixture to harden into a solid mass. The cement is the chemically active element, or matrix; the sand and stone are the inert elements, or aggregate.

Freemasonry, a religious and ethical movement that arose in the early 18th century in England and then spread to France, Germany, Spain, Russia, Denmark, Sweden, India, the USA, and other countries.
In Masonry, under the rubric of a moral doctrine proclaiming a “union of people on the basis of fraternity, love, equality, and mutual assistance,” ideas of bourgeois anticlericalism were fused with elements of religious mysticism. The movement originated in England (the creation of the Grand Lodge in 1717). In the Book of Constitutions, compiled by the London preacher James Anderson in 1723, the Mason was instructed to be “neither a foolish atheist, nor an irreligious freethinker,” support the civil authorities, and not participate in political movements. Rejecting church dogma and cult, Masons honor god as the “great architect of the universe” (in the spirit of deism), tolerate (as a rule) any religious faith, and incorporate in their teachings and ritual elements of Christianity, Judaism, and other religions. They (calling each other “brother”) are united in local organizations (lodges); the combined lodges on a national scale form the grand lodge, headed by the grand master. The name, organizational forms (lodge), and hierarchy (apprentice, fellowcraft, master, grand master), as well as symbolic signs (compasses, hammer, plumb, trowel, apron, and gloves) and other traditions, were copied by the Masons from the practice of the medieval guild associations (brotherhoods) of builders and bricklayers, particularly their upper stratum (architects, sculptors, and artists).
Originally the movement was bourgeois in character; in the second half of the 18th century many representatives of the Enlightenment participated in it. As an alternative to the feudal state system and the offical church, Masonry sought to create a secret worldwide organization for the purpose of peacefully unifying mankind in a religious fraternal union. Gradually (especially on the continent of Europe) the movement acquired a more aristocratic character. Elements of mysticism, which replaced the rationalistic spirit of early Masonry, and the striving to link Masonry with medieval knightly and mystical orders (such as Templars and Rosicrucians) gained importance. The earlier, comparatively simple, organization gave way to an increasingly complex hierarchy (involving up to 99 degrees in some Masonic movements), and a pompous ritual was created.
However, the social background of the movement’s participants, the underlying philosophical ideas, and the role of Masons in the political struggle were not uniform but varied significantly from country to country and from period to period. Its adherents included Prussian kings (from Frederick II to Frederick III), many English kings (George IV, Edward VII, and Edward VIII), the Swedish King Gustavus III, many American presidents (from Washington to Truman), the statesmen B. Franklin and W. Churchill, many philosophers and writers (G. E. Lessing, Voltaire, J. G. Fichte, J. W. von Goethe, C. M. Wieland, and J. G. von Herder), and the composers Mozart and Haydn. A. Weishaupt, who in 1776 created in Bavaria the order of Illuminati, tried to transform Masonry into a secret organization based on the ideas of the Enlightenment. In the early 19th century attempts were made to accommodate Masonry to the conspiratorial needs of the revolutionary movement (in Italy and Poland). The popes, who began issuing in 1738 a number of bulls condemning Masonry, carried on a struggle against it from a clerical position; Catholic Masons were excommunicated.
In the 1960’s there were nearly 8 million members of Masonic lodges in the world, of which 6 million were in Anglo-Saxon countries, chiefly the USA and Great Britain (other sources and calculations yield different data regarding the number of Masons).

In the years immediately preceding the Great French Revolution, the striving for realization of the Masonic utopia through the moral regeneration of people and for the solution of the conflict of poverty and wealth by means of alchemic experiments gained added impetus. For certain groups of Masons utopian ideals were of secondary importance, becoming a verbal screen for coming to terms with a landlord-dominated society; others, grouped around Novikov, sought to broaden their activity in support of public education; a third group (A. A. Petrov and N. M. Karamzin) became disappointed with Masonry and broke with it. Masonry was subjected simultaneously to persecution from the right (governmental repression and the mockery of Catherine IPs comedies) and sharp criticism from the left (A. N. Radishchev). In 1792, Masonry was banned in Russia.
Persecution ceased under Paul I, who sought a revival of various forms of medieval hierarchical organizations. The government of Alexander I allowed the Masonic lodges to function, striving to place them under supervision and even to use them for its own purposes. However, the hopes of the government proved to be unjustified, for there soon arose conspiratorial lodges of the “higher degrees,” while Masonry itself turned out to be closely linked with the Decembrists. (P. I. Pestel’, M. F. Orlov, and N. I. Turgenev, for example, retained an interest in Masonry up until the beginning of the 1820’s.) Disappointed with the tactics of conspiracy and shifting toward the idea of a military revolution, the Decembrists broke with Masonry; however, they condemned the ban imposed on Masonry by the government in 1822. In the subsequent history of Russian thought Masonry did not play a significant role, although frequent attempts at resurrecting it were made.

Construction of natural building stone or manufactured units such as brick, concrete block, adobe, glass block, or cast stone that is usually bonded with mortar. Masonry can be used structurally or as cladding or paving. It is strong in compression but requires the incorporation of reinforcing steel to resist tensile and flexural stresses. Masonry veneer cladding can be constructed with adhesive or mechanical bond over a variety of structural frame types and backing walls.
Masonry is noncombustible and can be used as both structural and protective elements in fire-resistive construction. It is durable against wear and abrasion, and most types weather well without protective coatings. The mass and density of masonry also provide efficient thermal and acoustical resistance.
Brick, concrete block, and stone are the most widely used masonry materials for both interior and exterior applications in bearing and nonbearing construction. Stone masonry can range from small rubble or units of ashlar (a hewn or squared stone) embedded in mortar, to mechanically anchored thin slabs, to ornately carved decorative elements. Granite, marble, and limestone are the most commonly used commercial building stones. Glass block can be used as security glazing or as elements to produce special daylighting effects. See Brick, Concrete, Glass
Masonry mortar is made from cement, sand, lime, and water. Masonry grout, a more fluid mixture of similar ingredients, is used to fill hollow cores and cavities and to embed reinforcing steel. Anchors and ties are usually of galvanized or stainless steel. Flashing may be of stainless steel, coated copper, heavy rubber sheet, or rubberized asphalt. See Grout, Mortar
