Sickle Cell Retinopathy
A sickle, bagging hook, reaping-hook or grasshook is a single-handed agricultural tool designed with variously curved blades and typically used for harvesting, or reaping, grain crops or cutting succulent forage chiefly for feeding livestock, either freshly cut or dried as hay. Falx was a synonym but was later used to mean any of a number of tools that had a curved blade that was sharp on the inside edge such as a scythe. Since the beginning of the Iron Age hundreds of region-specific variants of the sickle have evolved, initially of iron and later steel. This great diversity of sickle types across many cultures can be divided into smooth or serrated blades, both of which can be used for cutting either green grass or mature cereals using slightly different techniques. The serrated blade that originated in prehistoric sickles still dominates in the reaping of grain and is even found in modern grain-harvesting machines and in some kitchen knives.

Flint
Flint, occasionally flintstone, is a sedimentary cryptocrystalline form of the mineral quartz, categorized as the variety of chert that occurs in chalk or marly limestone. Flint was widely used historically to make stone tools and start fires. It occurs chiefly as nodules and masses in sedimentary rocks, such as chalks and limestones.''The Flints from Portsdown Hill''
Inside the nodule, flint is usually dark grey, black, green, white or brown in colour, and often has a glassy or waxy appearance. A thin layer on the outside of the nodules is usually different in colour, typically white and rough in texture. The nodules can often be found along s and

Druidry (modern)
Druidry, sometimes termed Druidism, is a modern spiritual or religious movement that promotes the cultivation of honorable relationships with the physical landscapes, flora, fauna, and diverse peoples of the world, as well as with nature deities, and spirits of nature and place. Theological beliefs among modern Druids are diverse; however, all modern Druids venerate the divine essence of nature. While there are significant interregional and intergroup variations in modern Druidry practice, Druids across the globe are unified by a core set of shared spiritual and devotional practices: meditation; prayer/conversation with deities and spirits; the use of extra-sensory methods of seeking wisdom and guidance; the use of nature-based spiritual frameworks to structure devotional practices and rituals; and a regular practice of nature connection and environmental stewardship work. Arising from the 18th century Romanticist movement in Britain, which glorified the ancient Celtic peopl ...

Natural History (Pliny)
The ''Natural History'' ( la, Naturalis historia) is a work by Pliny the Elder. The largest single work to have survived from the Roman Empire to the modern day, the ''Natural History'' compiles information gleaned from other ancient authors. Despite the work's title, its subject area is not limited to what is today understood by natural history; Pliny himself defines his scope as "the natural world, or life". It is encyclopedic in scope, but its structure is not like that of a modern encyclopedia. It is the only work by Pliny to have survived, and the last that he published. He published the first 10 books in AD 77, but had not made a final revision of the remainder at the time of his death during the AD 79 eruption of Vesuvius. The rest was published posthumously by Pliny's nephew, Pliny the Younger. The work is divided into 37 books, organised into 10 volumes. These cover topics including astronomy, mathematics, geography, ethnography, anthropology, human physiolog ...

Pliny The Elder
Gaius Plinius Secundus (AD 23/2479), called Pliny the Elder (), was a Roman author, naturalist and natural philosopher, and naval and army commander of the early Roman Empire, and a friend of the emperor Vespasian. He wrote the encyclopedic ''Naturalis Historia'' (''Natural History''), which became an editorial model for encyclopedias. He spent most of his spare time studying, writing, and investigating natural and geographic phenomena in the field. His nephew, Pliny the Younger, wrote of him in a letter to the historian Tacitus: Among Pliny's greatest works was the twenty-volume work ''Bella Germaniae'' ("The History of the German Wars"), which is no longer extant. ''Bella Germaniae'', which began where Aufidius Bassus' ''Libri Belli Germanici'' ("The War with the Germans") left off, was used as a source by other prominent Roman historians, including Plutarch, Tacitus and Suetonius. Tacitus—who many scholars agree had never travelled in Germania—used ''Bella Germani ...

Ritual Of Oak And Mistletoe
The ritual of oak and mistletoe is a Celtic religious ceremony, in which white-clad druids climbed a sacred oak, cut down the mistletoe growing on it, sacrificed two white bulls and used the mistletoe to make an elixir to cure infertility and the effects of poison.Pliny the Elder. '' Natural History'XVI, 95 The ritual, known from a single passage in Pliny's '' Natural History'', has helped shape the image of the druid in the popular imagination.Brunaux (2006), p. 47. Account by Pliny the Elder The only extant source for this ritual is a passage in the '' Natural History'' by Roman historian Pliny the Elder, written in the 1st century AD. Speaking of mistletoe, he writes: While Pliny does not indicate the source on which he based this account, French archaeologist Jean-Louis Brunaux ( fr) has argued for Posidonius of Rhodes, a polymath who flourished in the 1st century BC. Later influence and historiography Miranda Aldhouse-Green has argued that, although Pliny is the only aut ...

Druid
A druid was a member of the high-ranking class in ancient Celtic cultures. Druids were religious leaders as well as legal authorities, adjudicators, lorekeepers, medical professionals and political advisors. Druids left no written accounts. While they were reported to have been literate, they are believed to have been prevented by doctrine from recording their knowledge in written form. Their beliefs and practices are attested in some detail by their contemporaries from other cultures, such as the Romans and the Greeks. The earliest known references to the druids date to the 4th century BCE. The oldest detailed description comes from Julius Caesar's ''Commentarii de Bello Gallico'' (50s BCE). They were described by other Roman writers such as Cicero, Cicero (44) I.XVI.90. Tacitus, and Pliny the Elder. Following the Roman invasion of Gaul, the druid orders were suppressed by the Roman government under the 1st-century CE emperors Tiberius and Claudius, and had disappeare ...

1 (one, unit, unity) is a number representing a single or the only entity. 1 is also a numerical digit and represents a single unit of counting or measurement. For example, a line segment of ''unit length'' is a line segment of length 1. In conventions of sign where zero is considered neither positive nor negative, 1 is the first and smallest positive integer. It is also sometimes considered the first of the infinite sequence of natural numbers, followed by  2, although by other definitions 1 is the second natural number, following  0. The fundamental mathematical property of 1 is to be a multiplicative identity, meaning that any number multiplied by 1 equals the same number. Most if not all properties of 1 can be deduced from this. In advanced mathematics, a multiplicative identity is often denoted 1, even if it is not a number. 1 is by convention not considered a prime number; this was not universally accepted until the mid-20th century. Additionally, 1 is the s ...

Frankleben Hoard
The Frankleben hoard is a significant hoard deposit of the European Bronze Age, associated with the Unstrut group (associated with the Tumulus or early Urnfield culture (ca. 1500–1250 BC). The site is in the Geisel valley, formed by a minor tributary of the Saale River. It was discovered in 1946 in a brown coal pit near Frankleben, now a part of Braunsbedra municipality, Saxony-Anhalt, Germany. The hoard consists of three ceramic vessels, buried alongside one another. One of the vessels was destroyed by a coal dredger at the time of discovery. The finds consist of a total of about 45 kg of bronze artefacts, most of them sickles, alongside some axeheads. The discovery was made by the operator of the coal dredger, Anton Wesp, in the "Michael Vesta" pit (now flooded and part of ''Runstedter See'' south of Frankleben, just off the BAB 38 highway). Wesp's dredger destroyed the first vessel almost completely in June 1946 (find I). Wesp returned to the site on 5 July 1946 ...

Urnfield Culture
The Urnfield culture ( 1300 BC – 750 BC) was a late Bronze Age culture of Central Europe, often divided into several local cultures within a broader Urnfield tradition. The name comes from the custom of cremating the dead and placing their ashes in urns, which were then buried in fields. Over much of Europe, the Urnfield culture followed the Tumulus culture and was succeeded by the Hallstatt culture. Some linguists and archaeologists have associated this culture with the Proto-Celtic language, or a pre-Celtic language family. Chronology It is believed that in some areas, such as in southwestern Germany, the Urnfield culture was in existence around 1200 BC (beginning of Hallstatt A or Ha A), but the Bronze D Riegsee-phase already contains cremations. As the transition from the middle Bronze Age to the Urnfield culture was gradual, there are questions regarding how to define it. The Urnfield culture covers the phases Hallstatt A and B (Ha A and B) in Paul ...

Hoard
A hoard or "wealth deposit" is an archaeological term for a collection of valuable objects or artifacts, sometimes purposely buried in the ground, in which case it is sometimes also known as a cache. This would usually be with the intention of later recovery by the hoarder; hoarders sometimes died or were unable to return for other reasons (forgetfulness or physical displacement from its location) before retrieving the hoard, and these surviving hoards might then be uncovered much later by metal detector hobbyists, members of the public, and archaeologists. Hoards provide a useful method of providing dates for artifacts through association as they can usually be assumed to be contemporary (or at least assembled during a decade or two), and therefore used in creating chronologies. Hoards can also be considered an indicator of the relative degree of unrest in ancient societies. Thus conditions in 5th and 6th century Britain spurred the burial of hoards, of which the most famous a ...

Bronze Age Europe
The European Bronze Age is characterized by bronze artifacts and the use of bronze implements. The regional Bronze Age succeeds the Neolithic and Copper Age and is followed by the Iron Age. It starts with the Aegean Bronze Age in 3200 BC (succeeded by the Beaker culture), and spans the entire 2nd millennium BC (Unetice culture, Tumulus culture, Nordic Bronze Age, Terramare culture, Urnfield culture and Lusatian culture) in Northern Europe, lasting until c. 600 BC. History Aegean The Aegean Bronze Age begins around 3200 BC when civilizations first established a far-ranging trade network. This network imported tin and charcoal to Cyprus, where copper was mined and alloyed with the tin to produce bronze. Bronze objects were then exported far and wide and supported the trade. Isotopic analysis of the tin in some Mediterranean bronze objects indicates it came from as far away as Great Britain. Knowledge of navigation was well developed at this time and reached a peak of skill ...
