A compass rose, sometimes called a wind rose, rose of the winds or compass star, is a figure on a compass, map, nautical chart, or monument used to display the orientation of the cardinal directions (north, east, south, and west) and their intermediate points. It is also the term for the graduated markings found on the traditional magnetic compass. Today, a form of compass rose is found on, or featured in, almost all navigation systems, including nautical charts, non-directional beacons (NDB), VHF omnidirectional range (VOR) systems, global-positioning systems (GPS), and similar equipment.
In Europe ...seafarers in the Mediterranean came up with their own distinct 8-wind system. The mariners used names derived from the Mediterranean lingua franca, composed principally of Ligurian, mixed with Venetian, Sicilian, Provençal, Catalan, Greek and Arabic terms from around the Mediterranean basin.
(NE) Greco (or Bora)
(SE) Scirocco (or Exaloc)
(S) Ostro (or Mezzogiorno)
(SW) Libeccio (or Garbino)
(NW) Maestro (or Mistral)
The exact origin of the mariner's eight-wind rose is obscure. Only two of its point names (Ostro, Libeccio) have Classical etymologies, the rest of the names seem to be autonomously derived. Two Arabic words stand out: Scirocco (SE) from al-Sharq (الشرق – east in Arabic) and the variant Garbino (SW), from al-Gharb (الغرب – west in Arabic). This suggests the mariner's rose was probably acquired by southern Italian seafarers not from their classical Roman ancestors, but rather from Norman Sicily in the 11th to 12th centuries. The coasts of the Maghreb and Mashriq are SW and SE of Sicily respectively; the Greco (a NE wind), reflects the position of Byzantine-held Calabria-Apulia to the northeast of Arab Sicily, while the Maestro (a NW wind) is a reference to the Mistral wind that blows from the southern French coast towards northwest Sicily.
The 32-point compass used for navigation in the Mediterranean by the 14th century, had increments of 111⁄4° between points. Only the eight principal winds (N, NE, E, SE, S, SW, W, NW) were given special names. The eight half-winds just combined the names of the two principal winds, e.g. Greco-Tramontana for NNE, Greco-Levante for ENE, and so on. Quarter-winds were more cumbersomely phrased, with the closest principal wind named first and the next-closest principal wind second, e.g. "Quarto di Tramontana verso Greco" (literally, "one quarter wind from North towards Northeast", i.e. North by East), and "Quarto di Greco verso Tramontana" ("one quarter wind from NE towards N", i.e. Northeast by North). Boxing the compass (naming all 32 winds) was expected of all Medieval mariners.
Depiction on nautical charts
In the earliest medieval portolan charts of the 14th century, compass roses were depicted as mere collections of color-coded compass rhumb lines: black for the eight main winds, green for the eight half-winds and red for the sixteen quarter-winds. The average portolan chart had sixteen such roses (or confluence of lines), spaced out equally around the circumference of a large implicit circle.
The cartographer Cresques Abraham of Majorca, in his Catalan Atlas of 1375, was the first to draw an ornate compass rose on a map. By the end of the 15th century, Portuguese cartographers began drawing multiple ornate compass roses throughout the chart, one upon each of the sixteen circumference roses (unless the illustration conflicted with coastal details).
The points on a compass rose were frequently labeled by the initial letters of the mariner's principal winds (T, G, L, S, O, L, P, M). From the outset, the custom also began to distinguish the north from the other points by a specific visual marker. Medieval Italian cartographers typically used a simple arrowhead or circumflex-hatted T (an allusion to the compass needle) to designate the north, while the Majorcan cartographic school typically used a stylized Pole Star for its north mark. The use of the fleur-de-lis as north mark was introduced by Pedro Reinel, and quickly became customary in compass roses (and is still often used today). Old compass roses also often used a Christian cross at Levante (E), indicating the direction of Jerusalem from the point of view of the Mediterranean sea.
Coat of Arms of Portugal
At center, five escutcheon shields, forming a cross. On each shield are five round bezants (coins).
These five shields are arrayed in their cross on a larger shield. They are surrounded by seven golden, triple-towered castles.
Behind the shield, is an armillary sphere (which looks like a circle crossed by lines).
Present and past elements of the Coat of Arms of Portugal:
Quina (plural quinas) is the Portuguese term for a group of five things.
After the official recognition of the Kingdom of Portugal as an independent country in 1143 (it had been self declared as so in 1139), silver bezants were added to the blue cross of the shield, symbolising coins and the right of the monarch to issue currency, as leader of a sovereign state. Eventually, and given the enormous dynamism of medieval heraldry, it is believed that the shield degraded and lost some elements in battle, eventually losing the cross format. This is how King Sancho I inherited the shield from his father, Afonso Henriques, with the cross replaced by escutcheons with the silver bezants. A traditional legend explains that these escutcheons represent the five moor kings defeated by King Afonso I of Portugal in the battle of Ourique.
The number of silver bezants in each escutcheon varied extensively, with versions having represented from four up to eleven. In the late 14th century however, the number of bezants was fixed in five. Late explanations interpret them as the five wounds of Jesus Christ and/or the thirty pieces of silver (with the five bezants in the middle escutcheon counted twice), although this is highly improbable.
From the fixation of the number of bezants in five, the groups of the five escutcheons, each with five bezants of the Portuguese shield became popularly referred as quinas. By synecdoche, the term "Quinas" came to be used as an alternative designation of the coat of arms of Portugal and came even be used as a reference to anything that represents Portugal (e.g. the Flag of Portugal being often referred as the "Flag of the Quinas").
It was during the reign of Afonso III that the red bordure with golden castles (not towers, as some sources state) was added. Although the number of castles could vary between eight and twelve, Afonso IV would define them as twelve, and Sebastian I would finally fix them as seven. They supposedly represent the Moorish castles conquered by the Kingdom of Portugal during the Reconquista. Their origin is probably Castilian, but unlike Spanish castles, which usually have their gates coloured blue (hence opened), Portuguese castles were usually depicted with gold gates (hence closed). As a matter of fact, Afonso III was the second son of King Afonso II of Portugal and thus was not expected to inherit the throne, which was destined to go to his elder brother King Sancho II of Portugal. As a second son, the coat of arms of Afonso III included both the arms of his father and the arms of his mother Urraca of Castile, thus the Castillan red border with golden castillan castles, around the Portuguese shield inherited from his father.
An important element of Portuguese heraldry since the 15th century, the armillary sphere was many times used in Portuguese naval and colonial flags, mainly in Brazil. It was a navigation instrument used to calculate distances and represents the importance of Portugal during the Age of Discovery, as well as the vastness of its colonial empire when the First Republic was implemented.
Although it is commonly regarded as a "republican" element, as opposed to the monarchist crown in the blue/white flag (see Flag of Portugal), its usage predates the republic by several centuries; it was the personal emblem of Manuel I. Some flags of the monarchic era, such as the flag of the United Kingdom of Portugal, Brazil and the Algarves, already depicted armillary spheres. The incorporation of the armillary sphere into the 1816 flag of the United Kingdom of Portugal, Brazil and Algarves is related to the adoption of the first flag of the Kingdom of Brazil, an armillary sphere on a blue background.
The coat of arms sported different crowns during imperial rule of Portuguese and foreign crowns.
The two coins are in perfect condition. I'm happy to have them.
It's a beautiful coin in great condition.
so pretty! I want to make a pendant with this!
I’m so happy with the two compass rose coins I purchased from you. Both were in perfect shape and will make a great addition to the small collection I’ve put together over the years. They were packaged securely and shipped super fast. It’s almost that time of year for me to find unique coins with certain dates for a small memorial I do every autumn and I will only be looking in your shop this time and for as long as ever I can. Thank you for everything! You’re the best!
These are fantastic and just what I was looking for! Super fast shipping and I could not be happier thank you!
