Eclecticism in architecture is a 19th and 20th century architectural style in which a single piece of work incorporates eclecticism, a mixture of elements from previous historical styles to create something that is new and original. In architecture and interior design, these elements may include structural features, furniture, decorative motives, distinct historical ornament, traditional cultural motifs or styles from other countries, with the mixture usually chosen based on its suitability to the project and overall aesthetic value.
The term is also used of the many architects of the 19th and early 20th centuries who designed buildings in a variety of styles according to the wishes of their clients, or their own. The styles were typically revivalist, and each building might be mostly or entirely consistent within the style selected, or itself an eclectic mixture. Gothic Revival architecture, especially in churches, was most likely to strive for a relatively "pure" revival style from a particular medieval period and region, while other revived styles such as Neoclassical, Baroque, Palazzo style, Jacobethan, Romanesque and many others were likely to be treated more freely.
A vigesimal (/vɪˈdʒɛsɪməl/ vij-ESS-im-əl) or base-20 (base-score) numeral system is based on twenty (in the same way in which the decimal numeral system is based on ten). Vigesimal is derived from the Latin adjective vicesimus, meaning 'twentieth'.
The long hundred, also known as the great hundred or twelfty, is the number 120 (in base-10 Hindu-Arabic numerals) that was referred to as hund, hund-teontig, hundrað, hundrath, or hundred in Germanic languages prior to the 15th century, and is now known as one hundred (and) twenty, or six score. The number was translated into Latin in Germanic-speaking countries as centum (Roman numeral C), but the qualifier long is now added because English now uses hundred exclusively to refer to the number of five score (100) instead.
The long hundred was 120, but the long thousand was reckoned decimally as 10 long hundreds (1200).
19 (nineteen) is the natural number following 18 and preceding 20. It is a prime number.
21 (twenty-one) is the natural number following 20 and preceding 22.
The current century is the 21st century AD, under the Gregorian calendar.
