Azurite is a soft, deep blue copper mineral produced by weathering of copper ore deposits. Its primary use is for pigment: it gives a wide range of blues depending on the degree of fineness to which it was ground and its basic content of copper carbonate. Azurite is easily confused with lapis lazuli, another blue stone composed primarily of a different mineral, lazurite. Photo: Noodle snacks

"Our New 'First Lord' at Sea", an 1877 editorial cartoon from Punch mocking the appointment of William Henry Smith (right) as First Lord of the Admiralty, the governor of the Royal Navy of the United Kingdom. Smith had been a household name thanks to the W H Smith chain of booksellers and newsagents, and he had been a Member of Parliament for the previous ten years, but he had no naval or even military experience whatsoever. The following year, Gilbert and Sullivan's H.M.S. Pinafore would satirise him on similar grounds, and he became known as "Pinafore Smith" throughout the course of his three years in the post. Artist: John Tenniel; Restoration: Adam Cuerden

A macro view of a Gonia capitata fly feeding on honey, showing its proboscis and pedipalps (the two appendages protruding from the proboscis), two types of insect mouthparts. The proboscis actually comprises the labium, a quadrupedal structure, and a sponge-like labellum at the end. Flies eat solid food by secreting saliva and dabbing it over the food item. As the saliva dissolves the food, the solution is then drawn up into the mouth as a liquid. The labellum's surface is covered by minute food channels which form a tube leading to the esophagus, and food is drawn up the channels by capillary action. Photo: Richard Bartz

The flower of a Abutilon × hybridum 'Patrick Synge' cultivar, a hybrid shrub of unknown parentage. The common name "Chinese Lantern" is often used, though the same name is also applied to Physalis alkekengi. It is a popular group of hybrids that are semi-tropical, frost-tender shrubs typically growing 2–3 m (7–10 ft) tall. The lantern-like buds open to solitary, pendulous, bell- to cup-shaped flowers to 8 cm (3 in) diameter with five overlapping petals and significant staminal columns typical of the mallow family. Flowers come in red, pink, yellow, white and pastel shades. Lobed, maple-like, light green leaves are often variegated with white and yellow. Photo: Noodle snacks

A scene from Sir Walter Scott's 1817 historical novel Rob Roy, which tells the story of Frank Osbaldistone, the son of an English merchant who travels to Scotland to collect a debt stolen from his father. On the way he encounters the larger-than-life title character of Robert Roy MacGregor. Though Rob Roy is not the lead character (in fact the narrative does not move to Scotland until halfway through the book) his personality and actions are key to the story's development. The novel is a brutally realistic depiction of the social conditions in Highland and Lowland Scotland in the early 18th century. Engraving: Dalziel Brothers; Restoration: Adam Cuerden

Gawthorpe Hall is an Elizabethan house in Padiham, in the borough of Burnley, Lancashire, England. It was originally a pele tower, a strong square structure built in the 14th century as a defence against the invading Scots. Around 1600 a Jacobean mansion was dovetailed around the pele, but in 1850 Sir Charles Barry, who later designed the Houses of Parliament, redesigned it to its current state. Photo: Childzy

A scene from "The Canterville Ghost", Oscar Wilde's first published story, which is about an American family that moves into a haunted house in England. However, instead of being frightened of the eponymous ghost, they turn the tables and prank him, such as in this scene, where the twin boys have set up a butter-slide, causing the ghost to slip down the staircase. The story satirises both the unrefined tastes of Americans and the determination of the British to guard their traditions. Artist: Wallace Goldsmith; Restoration: Adam Cuerden

The frontispiece to A Memoir of Jane Austen, a biography of the author Jane Austen (1775–1817), written by her nephew James Edward Austen-Leigh and published 52 years after her death. Common to biographies written in the Victorian era, it did not attempt to unreservedly tell the story of the author's life, but instead kept much private information from the public. The Memoir generated popular interest in the works of Jane Austen, which only a literary elite had read up until that point. The art for the frontispiece took some liberties with the original painting, softening Austen's features in the Victorian style. Image: James Andrews, after Cassandra Austen

The Black Currawong (Strepera fuliginosa) is a large passerine bird native to Tasmania. One of three currawong species, it is closely related to the butcherbirds and Australian Magpie. It is a large crow-like bird, around 50 cm (20 in) long on average, with yellow irises, a heavy bill, and black plumage with white wing patches. It is similar in appearance to the Clinking Currawong, but the latter has a white rump and larger white wing patches. The Black Currawong is usually found in wetter eucalypt forests, in areas above 200 m (656 ft) altitude, mainly in the Central Highlands, with scattered records elsewhere in Tasmania and the surrounding islands.

Amethyst is a violet variety of quartz often used in jewelry. The color is a result of irradiation which causes the iron ions present as impurities in quartz to rearrange themselves in the crystal lattice. On exposure to heat, the irradiation effects can be partially cancelled and amethyst generally becomes yellow or even green. Photo: Noodle snacks

A poster for a 1908 American production of Aida, an opera by Giuseppe Verdi that premiered on December 24, 1871, to great acclaim at the Khedivial Opera House in Cairo, Egypt. However, Verdi was most dissatisfied that the audience consisted of invited dignitaries and critics, but no members of the general public. He therefore considered the European premiere, held at La Scala, Milan, to be its real premiere. Poster: Otis Lithograph Co; Restoration: Adam Cuerden

An engraving of an angel with the words Gloria in excelsis Deo et in terra pax ("Glory to God in the highest and peace on Earth"), the words angels sang when the birth of Christ was announced to shepherds, as recounted in Luke 2:14. This formed the basis of a doxology which is today known as Gloria in Excelsis Deo. A tradition recorded in the Liber Pontificalis states that Pope Telesphorus used the hymn at the Mass of Christmas Day in the 2nd century A.D., and it is still recited in its entirety in the Byzantine Rite Orthros service. The Gloria has been and still is sung to a wide variety of melodies, modern scholars having catalogued well over two hundred of them. Image: Dalziel Brothers, after J. R. Clayton

A portrait of a Plains Zebra (Equus quagga), the most common and widespread species of zebra. The unique stripes and behaviors of zebras make these among the animals most familiar to people. They can be found in a variety of habitats throughout Sub-Saharan Africa. The name "zebra" comes from the Old Portuguese word zevra which means "wild ass". Zebra stripes are typically vertical on the head, neck, forequarters, and main body, with horizontal stripes at the rear and on the legs of the animal. It was previously believed that zebras were white animals with black stripes. Embryological evidence, however, shows that the animal's background color is black and the white stripes are additions.

W. W. Denslow's illustration of "Baa, Baa, Black Sheep", a children's nursery rhyme that dates to 1744, when it was published in Tommy Thumb's Pretty Song Book. Since then, the words have remained mostly intact with few changes. The rhyme is sung to a variant of the 1761 French melody Ah! vous dirai-je, Maman, which is also used for "Twinkle Twinkle Little Star" and the alphabet song. As with many nursery rhymes, attempts have been made to find origins and meanings for the rhyme, but no theories have been definitively proven. Denslow's illustration accompanied a 1901 edition of Mother Goose. Restoration: Lise Broer

The knight's tour is a mathematical problem involving a knight on a chessboard. The knight is placed on the empty board and, moving according to the rules of chess, must visit each square exactly once. A knight's tour is called a closed tour if the knight ends on a square attacking the square from which it began (so that it may tour the board again immediately with the same path). Otherwise the tour is open. The depicted tour is an open tour, with shaded squares denoting where the knight has already visited. Animation: Ilmari Karonen
