Lateen-rig
A lateen (from French ''latine'', meaning "Latin") or latin-rig is a triangular sail set on a long yard mounted at an angle on the mast, and running in a fore-and-aft direction. The settee can be considered to be an associated type of the same overall category of sail. The lateen originated in the Mediterranean as early as the 2nd century CE, during Roman times, and became common there by the 5th century. The wider introduction of lateen rig at this time coincided with a reduction in the use of the Mediterranean square rig of the classical era. Since the performance of these two rigs is broadly similar, it is suggested that the change from one to the other was on cost grounds, since lateen used fewer components and had less cordage to be replaced when it wore out. Arab seafarers adopted the lateen rig at a later datethere is some limited archaeological evidence of lateen rig in the Indian Ocean in the 13th century CE and iconographic evidence from the 16th century. It has been ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The mast of a sailing vessel is a tall spar, or arrangement of spars, erected more or less vertically on the centre-line of a ship or boat. Its purposes include carrying sails, spars, and derricks, and giving necessary height to a navigation light, look-out position, signal yard, control position, radio aerial or signal lamp. Large ships have several masts, with the size and configuration depending on the style of ship. Nearly all sailing masts are guyed. Until the mid-19th century, all vessels' masts were made of wood formed from a single or several pieces of timber which typically consisted of the trunk of a conifer tree. From the 16th century, vessels were often built of a size requiring masts taller and thicker than could be made from single tree trunks. On these larger vessels, to achieve the required height, the masts were built from up to four sections (also called masts). From lowest to highest, these were called: lower, top, topgallant, and royal masts. Giving the lo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Settee (sail)
The settee sail was a lateen sail with the front corner cut off, giving it a quadrilateral shape. It can be traced back to Greco-Roman navigation in the Mediterranean in late antiquity; the oldest evidence is from a late-5th-century AD ship mosaic at Kelenderis, Cilicia. It lasted well into the 20th century as a common sail on Arab dhows. The settee sail requires a shorter yard than does the lateen, and both settee and lateen have shorter masts than square-rigged sails. Model of a sambuk with two settee sails Settees (or ''saëtia'') then were a sharp-prowed, single-decked merchant sailing vessel found in the Mediterranean (more in the Levant than in the Western Mediterranean), in the 18th and 19th centuries. The Spaniards also used them in the New World. Settees had two lateen-rigged masts, like xebecs or galleys, but carrying settee sails. They sailed well to windward and could sail downwind.

Graffito (archaeology)
A graffito (plural "graffiti"), in an archaeological context, is a deliberate mark made by scratching or engraving on a large surface such as a wall. The marks may form an image or writing. The term is not usually used for the engraved decoration on small objects such as bones, which make up a large part of the Art of the Upper Paleolithic, but might be used for the engraved images, usually of animals, that are commonly found in caves, though much less well known than the cave paintings of the same period; often the two are found in the same caves. In archaeology, the term may or may not include the more common modern sense of an "unauthorized" addition to a building or monument. Sgraffito, a decorative technique of partially scratching off a top layer of plaster or some other material to reveal a differently colored material beneath, is also sometimes known as "graffito".

Belisarius
Belisarius (; el, Βελισάριος; The exact date of his birth is unknown. – 565) was a military commander of the Byzantine Empire under the emperor Justinian I. He was instrumental in the reconquest of much of the Mediterranean territory belonging to the former Western Roman Empire, which had been lost less than a century prior. One of the defining features of Belisarius' career was his success despite varying levels of available resources. His name is frequently given as one of the so-called "Last of the Romans". He conquered the Vandal Kingdom of North Africa in the Vandalic War in nine months and conquered much of Italy during the Gothic War. He also defeated the Vandal armies in the battle of Ad Decimum and played an important role at Tricamarum, compelling the Vandal king, Gelimer, to surrender. During the Gothic War, despite being significantly outnumbered, he and his troops recaptured the city of Rome and then held out against great odds during the siege ...

Vandalic War
The Vandalic War was a conflict fought in North Africa between the forces of the Byzantine Empire and the Vandal Kingdom, Vandalic Kingdom of Carthage in 533–534. It was the first of Justinian I's wars of reconquest of the Western Roman Empire. The Vandals occupied Roman North Africa in the early 5th century, and established an independent kingdom there. Under their king, Geiseric, the Vandal navy carried out pirate attacks across the Mediterranean, Sack of Rome (455), sacked Rome and defeated a Roman invasion in 468. After Geiseric's death, relations with the Eastern Roman Empire normalized, although tensions flared up occasionally due to the Vandals' adherence to Arianism and their persecution of the Nicene native population. In 530, a palace coup in Carthage overthrew the pro-Roman Hilderic and replaced him with his cousin Gelimer. The Eastern Roman emperor Justinian took this as a pretext to intervene in Vandal affairs, and after securing the eastern frontier with Sassani ...

Iconography
Iconography, as a branch of art history, studies the identification, description and interpretation of the content of images: the subjects depicted, the particular compositions and details used to do so, and other elements that are distinct from artistic style. The word ''iconography'' comes from the Greek ("image") and ("to write" or ''to draw''). A secondary meaning (based on a non-standard translation of the Greek and Russian equivalent terms) is the production or study of the religious images, called "icons", in the Byzantine and Orthodox Christian tradition (see Icon). This usage is mostly found in works translated from languages such as Greek or Russian, with the correct term being "icon painting". In art history, "an iconography" may also mean a particular depiction of a subject in terms of the content of the image, such as the number of figures used, their placing and gestures. The term is also used in many academic fields other than art history, for example semiotics ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Harbour Of Eleutherios
The Harbour of Eleutherios (), originally known as the Harbour of Theodosius ( la, Portus Theodosiacus, ) was one of the ports of ancient Constantinople, the capital of the Byzantine Empire, located beneath the modern Yenikapi neighbourhood of Istanbul, Turkey. It was built at the mouth of the Lycus watercourse that ran through the city to the Propontis (the Sea of Marmara). The harbour was built in the late 4th century, during the reign of Theodosius I, and was the city's major point of trade in Late Antiquity. It continued to be used until the 11th century. Silt from the Lycus creek eventually filled the harbour entirely and the area was later transformed for agricultural use due to the effects of upstream erosion and deposition. In Ottoman times, the area was built over. The harbour was located on the south side of the peninsula on which the city is built, on the shore of the Sea of Marmara. The other harbours on the southern coast of the city were the Harbour of Julian and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rigging
Rigging comprises the system of ropes, cables and chains, which support a sailing ship or sail boat's masts—''standing rigging'', including shrouds and stays—and which adjust the position of the vessel's sails and spars to which they are attached—the ''running rigging'', including halyards, braces, sheets and vangs. Etymology According to the Encyclopædia Britannica Eleventh Edition "rigging" derives from Anglo-Saxon ''wrigan'' or ''wringing'', "to clothe". The same source points out that "rigging" a sailing vessel refers to putting all the components in place to allow it to function, including the masts, spars, sails and the rigging. Types of rigging Rigging is divided into two classes, ''standing'', which supports the mast (and bowsprit), and ''running'', which controls the orientation of the sails and their degree of reefing. Configurations differ for each type of rigging, between ''fore-and-aft rigged'' vessels and ''square-rigged'' vessels. Standing Standin ...
