Author in the context of John Langdon-Davies

An artist is a person engaged in creating art, or practicing the arts. The most common usage in everyday speech and academic discourse refers to a practitioner in the visual arts only.

However, the term is also very widely used in the entertainment business to refer to actors, musicians, singers, dancers , and other performers. The French word artiste is sometimes used in English in this context, although this has become old-fashioned. The use of the term "artist" to describe writers is valid, but less common, and mostly restricted to contexts such as critics' reviews; "author" is generally used instead.

A book is a written work of substantial length by one or more authors. They can be distributed in various forms including as printed books, audiobooks, and electronic books (ebooks). Books are broadly classified into fiction (containing invented content, often narratives) and non-fiction (containing content intended as factual truth).

The term can also refer to the physical or electronic object that contains such a work. Modern printed books are typically composed of many pages bound together and protected by a cover. This is known as the codex format. Codices have been created for centuries and were used even before printed books were available to create manuscript books by hand. Older formats include scrolls and clay tablets.

Charles Lutwidge Dodgson (27 January 1832 – 14 January 1898), better known by his pen name Lewis Carroll, was an English author, poet, mathematician, photographer and reluctant Anglican deacon. His most notable works are Alice's Adventures in Wonderland (1865) and its sequel Through the Looking-Glass (1871), some of the most important examples of Victorian literature. He was noted for his facility with word play, logic, and fantasy. His poems Jabberwocky (1871) and The Hunting of the Snark (1876) are classified in the genre of literary nonsense. Some of Alice's nonsensical wonderland logic reflects his published work on mathematical logic.

Carroll came from a family of high-church Anglicans, and pursued his clerical training at Christ Church, Oxford, where he lived for most of his life as a scholar, teacher and (necessarily for his academic fellowship at the time) Anglican deacon. Alice Liddell – a daughter of Henry Liddell, the Dean of Christ Church – is widely identified as the original inspiration for Alice in Wonderland, though Carroll always denied this.

A poet is a person who studies and creates poetry. Poets may describe themselves as such or be described as such by others. A poet might simply be the creator (thinker, songwriter, writer, or author) who creates (composes) poems (oral or written), or someone who also performs their art to an audience.

The work of a poet is essentially one of communication, expressing ideas either in a literal sense (such as describing a specific event or place) or metaphorically. Poets have existed since prehistory, in nearly all languages, and have produced works that vary greatly in different cultures and periods. Throughout each civilization and language, poets have used various styles that have changed over time, resulting in countless poets as diverse as the literature that (since the advent of writing systems) they have produced.

A pen name or nom-de-plume is a pseudonym (or, in some cases, a variant form of a real name) adopted by an author and printed on the title page or by-line of their works in place of their real name.

A pen name may be used to make the author's name more distinctive, to disguise the author's gender, to distance the author from their other works, to protect the author from retribution for their writings, to merge multiple persons into a single identifiable author, or for any of several reasons related to the marketing or aesthetic presentation of the work.

A documentary film (often described simply as a documentary) is a nonfiction, motion picture intended to "document reality, primarily for instruction, education or maintaining a historical record". The American author and media analyst Bill Nichols has characterized the documentary in terms of "a filmmaking practice, a cinematic tradition, and mode of audience reception [that remains] a practice without clear boundaries".

Research into information gathering, as a behavior, and the sharing of knowledge, as a concept, has noted how documentary movies were preceded by the notable practice of documentary photography. This has involved the use of singular photographs to detail the complex attributes of historical events and continues to a certain degree to this day, with an example being the conflict-related photography achieved by popular figures such as Mathew Brady during the American Civil War. Documentary movies evolved from the creation of singular images in order to convey particular types of information in depth, using film as a medium.

Servius, distinguished as Servius the Grammarian (Latin: Servius or Seruius Grammaticus), was a late fourth-century and early fifth-century grammarian. He earned a contemporary reputation as the most learned man of his generation in Italy; he authored a set of commentaries on the works of Virgil. These works, In Tria Virgilii Opera Expositio ("Exposition on Three Works of Virgil"), Commentarii in Virgilium ("Commentaries on Virgil"), Commentarii in Vergilii Opera ("Commentaries on the Works of Vergil"), or Vergilii Carmina Commentarii ("Commentaries on the Poems of Virgil"), constituted the first incunable to be printed at Florence, by Bernardo Cennini, in 1471.

In the Saturnalia of Macrobius, Servius appears as one of the interlocutors; allusions in that work and a letter from Symmachus to Servius indicate that he was not a convert to Christianity.

A book is a written work of substantial length created by one or more authors. They can be distributed in various forms such as printed books, audiobooks, and electronic books (ebooks). Books are broadly classified into fiction, containing invented narrative or other imaginary content; and non-fiction, containing content intended as factual truth.

The term may also refer to the physical or electronic object containing such a work. Modern books are typically printed in a codex format, composed of many pages bound together and protected by a cover. Before the wide adoption of the modern printing press, codices were used to create handwritten manuscripts. Older writing mediums include scrolls and clay tablets.

A novelist is an author or writer of novels, though often novelists also write in other genres of both fiction and non-fiction. Some novelists are professional novelists, thus make a living writing novels and other fiction, while others aspire to support themselves in this way or write as an avocation. Most novelists struggle to have their debut novel published, but once published they often continue to be published, although very few become literary celebrities, thus gaining prestige or a considerable income from their work.

Praxiteles (/prækˈsɪtɪliːz/; Greek: Πραξιτέλης) of Athens, the son of Cephisodotus the Elder, was the most renowned of the Attic sculptors of the 4th century BC. He was the first to sculpt the nude female form in a life-size statue. While no indubitably attributable sculpture by Praxiteles is extant, numerous copies of his works have survived; several authors, including Pliny the Elder, wrote of his works; and coins engraved with silhouettes of his various famous statuary types from the period still exist.

A supposed relationship between Praxiteles and his beautiful model, the Thespian courtesan Phryne, has inspired speculation and interpretation in works of art ranging from painting (Gérôme) to comic opera (Saint-Saëns) to shadow play (Donnay).

Florence Crauford Grove (12 March 1838 – 17 August 1902) was an English mountaineer and author, sometimes known as F. Crauford Grove. He led the first expedition to ascend the higher summit of Mount Elbrus and was at one time president of the Alpine Club.

Montague Rhodes James OM FBA (1 August 1862 – 12 June 1936) was an English medievalist scholar and author who served as provost of King's College, Cambridge (1905–1918), and of Eton College (1918–1936) as well as Vice-Chancellor of the University of Cambridge (1913–1915). James's scholarly work is still highly regarded, but he is best remembered for his ghost stories, which are considered by many critics and authors as the finest in the English language and widely influential on modern horror.

James originally read the stories to friends and select students at Eton and Cambridge as Christmas Eve entertainments, and received wider attention when they were published in the collections Ghost Stories of an Antiquary (1904), More Ghost Stories of an Antiquary (1911), A Thin Ghost and Others (1919), A Warning to the Curious and Other Ghost Stories (1925), and the hardback omnibus The Collected Ghost Stories of M. R. James (1931). James published a further three stories before his death in 1936, and seven previously unpublished or unfinished stories appeared in The Fenstanton Witch and Others: M. R. James in Ghosts and Scholars (1999), all of which have been included in later collections.

Biographers are authors who write an account of another person's life, while autobiographers are authors who write their own biography.

A programmer, computer programmer or coder is an author of computer source code – someone with skill in computer programming.

A pseudepigraph (also anglicized as "pseudepigraphon") is a falsely attributed work, a text whose claimed author is not the true author, or a work whose real author attributed it to a figure of the past. The name of the author to whom the work is falsely attributed is often prefixed with the particle "pseudo-", such as "pseudo-Aristotle" or "pseudo-Dionysius." These terms refer to the anonymous authors of works falsely attributed to Aristotle and Dionysius the Areopagite, respectively.

In biblical studies, the term pseudepigrapha can refer to an assorted collection of Jewish religious works thought to be written c. 300 BCE to 300 CE. They are distinguished by Protestants from the deuterocanonical books (Catholic and Orthodox) or Apocrypha (Protestant), the books that appear in extant copies of the Septuagint in the fourth century or later and the Vulgate, but not in the Hebrew Bible or in Protestant Bibles. In Catholic usage, the Old Testament books accepted by the Catholic Church are referred to as the deuterocanonical books, and Catholic writers commonly reserve the word apocrypha for spurious or noncanonical writings rather than for the deuterocanon. In addition, two books considered canonical in the Orthodox Tewahedo churches, the Book of Enoch and Book of Jubilees, are noncanonical in Catholic and Eastern Orthodox canons and are classified by most scholars among the Old Testament pseudepigrapha.
