Original in the context of Shakespeare

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.

In copyright law, a derivative work is an expressive creation that includes major copyrightable elements of a first, previously created original work (the underlying work). The derivative work becomes a second, separate work independent from the first. The transformation, modification or adaptation of the work must be substantial and bear its author's personality sufficiently to be original and thus protected by copyright. Translations, cinematic adaptations and musical arrangements are common types of derivative works.

Most countries' legal systems seek to protect both original and derivative works. They grant authors the right to impede or otherwise control their integrity and the author's commercial interests. Derivative works and their authors benefit in turn from the full protection of copyright without prejudicing the rights of the original work's author.
