Quincunx (coin)
The ''quincunx'' was a bronze coin minted during the Roman Republic. It was not part of the standard coinage of the Roman monetary system. The quincunx was produced only during the Second Punic War (218 to 204 BC), by mints at Luceria (mod. Lucera), Teate (mod. Chieti), Larinum (mod. Larino), and northern Apulia. After the defeat of Cannae during the Second Punic War, a coin with the same value was minted in Capua. The word ''quincunx'' comes from Latin '' quinque'' meaning "five" and '' uncia'' meaning "one-twelfth", since the coin was valued at five-twelfths of a bronze '' as'' (also called a ''libra''). Its value was sometimes represented by a pattern of five dots arranged at the corners and the center of a square, like the pips of a die. So, this pattern also came to be called quincunx A quincunx ( ) is a geometry, geometric pattern consisting of five points arranged in a cross, with four of them forming a Square (geometry), square or rectangle and a fifth at its cente ...

As (coin)
The ' (: '), occasionally ''assarius'' (: ''assarii''; ), was a bronze, and later copper, coin used during the Roman Republic and Roman Empire. Republican era coinage The Romans replaced the usage of Greek coins, first by bronze ingots, then by disks known as the ''aes rude''. The system thus named ''as'' was introduced in ca. 280 BC as a large cast bronze coin during the Roman Republic. The following fractions of the were also produced: the (), (), (), (), (), (), (, also a common weight unit), and (), as well as multiples of the ''as'', the (2), (2), and (3). After the ''as'' had been issued as a cast coin for about seventy years, and its weight had been reduced in several stages, a ''as'' was introduced (meaning that it weighed one-sixth of a pound). At about the same time a silver coin, the ''denarius'', was also introduced. Earlier Roman silver coins had been struck on the Greek weight standards that facilitated their use in southern Italy and across th ...

Five-point Stencil
In numerical analysis, given a square grid in one or two dimensions, the five-point stencil of a point in the grid is a stencil made up of the point itself together with its four "neighbors". It is used to write finite difference approximations to derivatives at grid points. It is an example for numerical differentiation. In one dimension In one dimension, if the spacing between points in the grid is ''h'', then the five-point stencil of a point ''x'' in the grid is : \. 1D first derivative The first derivative of a function ''f'' of a real variable at a point ''x'' can be approximated using a five-point stencil as: :f'(x) \approx \frac The center point ''f''(''x'') itself is not involved, only the four neighboring points. Derivation This formula can be obtained by writing out the four Taylor series of f(x \pm h) and f(x \pm 2h) at the point a, up to terms of ''h''3 (or up to terms of ''h''5 to get an error estimation as well), evaluating each series at a = x \mp h and a = x ...

Five Dots Tattoo

Saltire
A saltire, also called Saint Andrew's Cross or the crux decussata, is a Heraldry, heraldic symbol in the form of a diagonal cross. The word comes from the Middle French , Medieval Latin ("stirrup").

Notable 19th-century usage includes some of the flags of the Confederate States of America. It is also used in the flag of Jamaica and on Seal (emblem), seals, and as a Charge (heraldry), heraldic charge in Coat of arms, coats of arms. The term saltirewise or in saltire refers to heraldic charges arranged as a diagonal cross. The Escutcheon (heraldry), shield may also be Division of the field, divided per saltire, i.e. diagonally.
