Thomas Hope (c. 1770 - February 3, 1831), was a British art collector and author, best known for Anastasius.

He was born in London about 1770, the eldest son of John Hope of Amsterdam, and was descended from a branch of an old Scottish family who for several generations were merchants in London and Amsterdam. Aged about eighteen, he began a tour through Europe, Asia and Africa, where he interested himself especially in architecture and sculpture, making a large collection of artefacts which attracted his attention. On his return to London in about 1796 he purchased a house in Duchess Street, Cavendish Square, which he fitted out in a very elaborate style, from drawings made by himself.

In 1807 he published sketches of his furniture, in a folio volume, entitled Household Furniture and Interior Decoration, which had considerable influence and brought about a change in the upholstery and interior decoration of houses. This was in spite of some sarcastic remarks from Byron. Hope's furniture designs were in the pseudo-classical manner generally called "English Empire". It was sometimes extravagant, and often heavy, but was much more restrained than the wilder and later flights of Thomas Sheraton in this style. At the best, however, it was a not very inspiring mixture of Egyptian and Roman motives. In 1809 he published the Costumes of the Ancients, and in 1812 Designs of Modern Costumes, works which display a large amount of antiquarian research.

He was also, as his father had been the elder Hope's country house near Haarlem was crowded with fine pictures, a munificent patron of the highest forms of art, and both at his London house and his country seat at Deepdene near Dorking he formed large collections of paintings, sculpture and antiques. Deepdene in his day became a famous resort of men of letters as well as of people of fashion, and among the luxuries suggested by his fine taste was a miniature library in several languages in each bedroom. Bertel Thorvaldsen, the Danish sculptor, was indebted to him for the early recognition of his talents, and he also gave frequent employment to Francis Legatt Chantrey and John Flaxman; it was to his order that the latter illustrated Dante.

In 1819 he published anonymously his novel, Anastasius, or Memoirs of a Modern Greek, written at the close of the 18th century, a work which, chiefly on account of the novel character of its subject, caused a great sensation. It was at first generally attributed to Lord Byron, who told Marguerite, Countess of Blessington, that he wept bitterly on reading it because he had not written it and Hope had. Although remarkable for the acquaintance it displays with Eastern life, and distinguished by considerable imaginative vigour and much graphic and picturesque descripion, its paradoxes are not so striking as those of Lord Byron. Despite some eloquent and forcible passages, it was ascribed to Byron only because of the general type of character to which its hero belonged.

Hope was the author of two works published posthumously -- the Origin and Prospect of Man (1831), in which his speculations diverged widely from the usual orthodox opinions, and an Historical Essay on Architecture (1835), an elaborate description of the architecture of the middle ages, illustrated by drawings made by himself in Italy and Germany. He is commonly known in literature as "Anastasius Hope". He married (1806) Louisa de la Poe Beresford, daughter of Lord Decies, archbishop of Tuarn.
