Works of art in the context of "Artistic expression"

Art is a diverse range of cultural activity centered around works utilizing creative or imaginative talents, which are expected to evoke a worthwhile experience, generally through an expression of emotional power, conceptual ideas, technical proficiency, or beauty.

There is no generally agreed definition of what constitutes art, and its interpretation has varied greatly throughout history and across cultures. In the Western tradition, the three classical branches of visual art are painting, sculpture, and architecture. Theatre, dance, and other performing arts, as well as literature, music, film and other media such as interactive media, are included in a broader definition of "the arts". Until the 17th century, art referred to any skill or mastery and was not differentiated from crafts or sciences. In modern usage after the 17th century, where aesthetic considerations are paramount, the fine arts are separated and distinguished from acquired skills in general, such as the decorative or applied arts.

A memorial is an object or place which serves as a focus for the memory or the commemoration of something, usually an influential, deceased person or a historical, tragic event. Popular forms of memorials include landmark objects such as homes or other sites, or works of art such as sculptures, statues, fountains or parks. Larger memorials may be known as monuments.

Glass art refers to individual works of art that are substantially or wholly made of glass. It ranges in size from monumental works and installation pieces to wall hangings and windows, to works of art made in studios and factories, including glass jewelry and tableware.

As a decorative and functional medium, glass was extensively developed in Egypt and Assyria. Glassblowing was perhaps invented in the 1st century BC, and featured heavily in Roman glass, which was highly developed with forms such as the cage cup for a luxury market. Islamic glass was the most sophisticated of the early Middle Ages. Then the builders of the great Norman and Gothic cathedrals of Europe took the art of glass to new heights with the use of stained glass windows as a major architectural and decorative element. Glass from Murano, in the Venetian Lagoon, (also known as Venetian glass) is the result of hundreds of years of refinement and invention. Murano is still held as the birthplace of modern glass art.

Provenance (from French provenir 'to come from/forth') is the chronology of the ownership, custody or location of a historical object. The term was originally mostly used in relation to works of art, but is now used in similar senses in a wide range of fields, including archaeology, paleontology, archival science, economy, computing, and scientific enquiry in general.

The primary purpose of tracing the provenance of an object or entity is normally to provide contextual and circumstantial evidence for its original production or discovery, by establishing, as far as practicable, its later history, especially the sequences of its formal ownership, custody and places of storage. The practice has a particular value in helping authenticate objects. Comparative techniques, expert opinions and the results of scientific tests may also be used to these ends, but establishing provenance is essentially a matter of documentation. The term dates to the 1780s in English. Provenance is conceptually comparable to the legal term chain of custody.

A uniform title in library cataloging is a distinctive title assigned to a work which either has no title or has appeared under more than one title. Establishing a uniform title is an aspect of authority control. The phrases conventional title and standard title are sometimes used; Resource Description and Access uses preferred title; while the 2009 Statement of International Cataloguing Principles deprecates "uniform title" in favour of authorized access point.

There are many instances in which a uniform title can be used. Anonymous works such as sacred texts and folk tales may lack an obvious title: for instance, the Bible, Epic of Gilgamesh, Beowulf, or the Chanson de Roland. Works of art and music may contain no text that can be used for reference. A uniform title allows all versions of the work to collate under one title and will reference all of the items to which the uniform title applies.
