Replica in the context of "Cornerstone"

The Antikythera mechanism (/ˌæntɪkɪˈθɪərə/ AN-tik-ih-THEER-ə, US also /ˌæntaɪkɪˈ-/ AN-ty-kih-) is an ancient Greek hand-powered orrery (model of the Solar System). It is the oldest known example of an analogue computer. It could be used to predict astronomical positions and eclipses decades in advance. It could also be used to track the four-year cycle of athletic games similar to an olympiad, the cycle of the ancient Olympic Games.

The artefact was among wreckage retrieved from a shipwreck off the coast of the Greek island Antikythera in 1901. In 1902, during a visit to the National Archaeological Museum in Athens, it was noticed by Greek politician Spyridon Stais as containing a gear, prompting the first study of the fragment by his cousin, Valerios Stais, the museum director. The device, housed in the remains of a wooden-framed case of (uncertain) overall size 34 cm × 18 cm × 9 cm (13.4 in × 7.1 in × 3.5 in), was found as one lump, later separated into three main fragments which are now divided into 82 separate fragments after conservation efforts. Four of these fragments contain gears, while inscriptions are found on many others. The largest gear is about 13 cm (5 in) in diameter and originally had 223 teeth. All these fragments of the mechanism are kept at the National Archaeological Museum, along with reconstructions and replicas, to demonstrate how it may have looked and worked.

The spatha was a type of straight and long sword, measuring between 0.5 and 1 metre (20 and 40 inches), with a handle length of between 18 and 20 centimetres (7 and 8 inches), in use in the territory of the Roman Empire during the 1st to 6th centuries AD. Later swords, from the 7th to 10th centuries, like the Viking swords, are recognizable derivatives and sometimes subsumed under the term spatha.

The Roman spatha was used in war and in gladiatorial fights. The spatha of literature appears in the Roman Empire in the 1st century AD as a weapon used by presumably Celtic auxiliaries and gradually became a standard heavy infantry weapon by the 3rd century AD, relegating the gladius to use as a light infantry weapon. The spatha apparently replaced the gladius in the front ranks, giving the infantry more reach when thrusting. While the infantry version had a long point, versions carried by the cavalry had a rounded tip that prevented accidental stabbing of the cavalryman's own foot or horse.

Originality is the aspect of created or invented works that distinguish them from reproductions, clones, forgeries, or substantially derivative works. The modern idea of originality is according to some scholars tied to Romanticism, by a notion that is often called romantic originality. The validity of "originality" as an operational concept has been questioned. For example, there is no clear boundary between "derivative" and "inspired by" or "in the tradition of."

The concept of originality is both culturally and historically contingent. For example, unattributed reiteration of a published text in one culture might be considered plagiarism but in another culture might be regarded as a convention of veneration. At the time of Shakespeare, it was more common to appreciate the similarity with an admired classical work, and Shakespeare himself avoided "unnecessary invention". It wasn't until the start of the 18th century that the concept of originality became an ideal in Western culture.

Fushimi Castle (伏見城, Fushimi-jō), also known as Momoyama Castle (桃山城, Momoyama-jō) or Fushimi-Momoyama Castle, is a Japanese castle located in Fushimi Ward, Kyoto.

Fushimi Castle was constructed from 1592 to 1594 by Toyotomi Hideyoshi at the end of the Sengoku period as his retirement residence. Fushimi Castle was destroyed in the 1596 Keichō–Fushimi earthquake and rebuilt before eventually being demolished in 1623 and its site later used for the tomb of Emperor Meiji. The current Fushimi Castle is a replica constructed in 1964 near the original site in Fushimi.

Ulysses and the Sirens is a 1909 oil painting by Herbert James Draper measuring 69.25 in × 84 in (175.9 cm × 213.4 cm). It is now in the Ferens Art Gallery in Kingston upon Hull, England. The gallery bought the painting from Draper in 1910 for £600. Draper also painted a reduced replica that is now in the Leeds Art Gallery.

The subject of the painting is an episode in the epic poem Odyssey by Homer in which Ulysses is tormented by the voices of Sirens, although there are only two Sirens in Homer's poem and they stay in a meadow. The painting depicts Ulysses tied to the mast and forcibly attendant to the Sirens' seductions.

The Sargon Stele was found in the autumn of 1845 in Cyprus on the site of the former city-kingdom of Kition, in present-day Larnaca to the west of the old harbour of Kition in the archaeological site of Bamboula. The language on the stele is Assyrian Akkadian.

The stele was placed there during the time Sargon II (r. 722–705 BC) ruled the Neo-Assyrian Empire (935–605 BC). It was offered for sale to the British Museum, which bid 20 £. Ludwig Ross offered 50 £ for the stele and it was shipped to a museum in Berlin where it remains at the Berlin State Museums. Together with the stele was found a gilded silver plakette, that today is located at the Louvre. A replica of the stele is on display in the Larnaca District Museum.

Fishing bait is any luring substance used specifically to attract and catch fish, typically when angling with a hook and line. There are generally two types of baits used in angling: hookbaits, which are directly mounted onto fish hooks and are what the term "fishing bait" typically refers to; and groundbaits, which are scattered separately into the water as an "appetizer" to attract the fish nearer to the hook. Despite the bait's sole importance is to provoke a feeding response out of the target fish, the way how fish react to different baits is quite poorly understood.

Fishing baits can be grouped into two broad categories: natural baits and artificial baits. Traditionally, fishing baits are natural food or prey items (live or dead) that are already present in the fish's normal diet (e.g. worms, insects, crustaceans and smaller bait fish), and such baits are both procured from and used within the same environment. Artificial baits, conversely, are not naturally acquired and must involve some kind of production process. These can be processed foods (e.g. bread, cheese, dough, cutlets, fish food or pet food pellets, etc.), commercially made feed mixtures (e.g. boilies), or imitative replica "fake foods" made of inedible materials known as lures (e.g plastic worm, swimbaits, spoons, stickbaits, hybrid spinners or even bionic robot fish). The variety of baits that a fisherman may choose is dictated mainly by the target species and by its habitat, as well as personal preference. Both natural and artificial baits frequently demonstrate similar efficiency if chosen adequately for the target fish. The overall bait type, size and techniques used will affect the efficiency and yield when fishing.

Reconstruction in architectural conservation is the returning of a place to a known earlier state by the introduction of new materials. It is related to the architectural concepts of restoration (repairing existing building fabric) and preservation (the prevention of further decay), wherein the most extensive form of reconstruction is creating a replica of a destroyed building.

More narrowly, such as under the Secretary of Interior's Standards in the United States, "reconstruction" is "the act or process of depicting, using new construction, the form, features, and detailing of a non-surviving site, landscape, building, structure, or object to replicate its appearance at a specific time and in its historic location".
