Sickle in the context of "Yaz culture"

Yellow River civilization, Huanghe civilization or Huanghe Valley civilization (Chinese: 黃河文明), Hwan‐huou civilization is an ancient Chinese civilization that prospered in the middle and lower basin of the Yellow River. Agriculture was started in the flood plain of the Yellow River, and before long, through flood control and the irrigation of the Yellow River, cities were developed and political power found reinforcement. One of the "four major civilizations of the ancient world", it is often included in textbooks of East Asian history, but the idea of including only the Yellow River civilization as one of the four biggest ancient civilizations has become outdated as a result of the discovery of other early cultures in China, such as the Yangtze and Liao civilizations. The area saw the Yangshao and Longshan cultures of the Neolithic era and developed into the bronze ware culture of the Shang and Zhou dynasties.

A crescent shape (/ˈkrɛsənt/, UK also /ˈkrɛzənt/) is a symbol or emblem used to represent the lunar phase (as it appears in the northern hemisphere) in the first quarter (the "sickle moon"), or by extension a symbol representing the Moon itself.

In Hindu iconography, Shiva is often shown wearing a crescent moon on his head, symbolising his control over time, as well as his attributes of both creation and destruction.

In ancient Greek religion and mythology, Cronus, Cronos, or Kronos (/ˈkroʊnəs/ or /ˈkroʊnɒs/; Ancient Greek: Κρόνος) was the leader and youngest of the Titans, the children of Gaia (Earth) and Uranus (Sky). He overthrew his father and ruled during the mythological Golden Age until he was overthrown by his son Zeus and imprisoned in Tartarus. According to Plato, however, the deities Phorcys, Cronus, and Rhea were the eldest children of Oceanus and Tethys.

Cronus was usually depicted with a harpe, scythe, or sickle, which was the instrument he used to castrate and depose Uranus, his father. Cronus was likely originally a harvest god, which is why in many regions of Greece the month of the harvest was named Cronion after him. In Athens, on the twelfth day of the Attic month of Hekatombaion, a festival called Kronia was held in honour of Cronus to celebrate the harvest, suggesting that, as a result of his association with the virtuous Golden Age, Cronus continued to preside as a patron of the harvest. Cronus was also identified in classical antiquity with the Roman deity Saturn.

Harvesting is the process of collecting plants, animals, or fish (as well as fungi) as food, especially the process of gathering mature crops, and "the harvest" also refers to the collected crops. Reaping is the cutting of grain or pulses for harvest, typically using a scythe, sickle, or reaper. On smaller farms with minimal mechanization, harvesting is the most labor-intensive activity of the growing season. On large mechanized farms, harvesting uses farm machinery, such as the combine harvester. Automation has increased the efficiency of both the seeding and harvesting processes. Specialized harvesting equipment, using conveyor belts for gentle gripping and mass transport, replaces the manual task of removing each seedling by hand. The term "harvesting" in general usage may include immediate postharvest handling, including cleaning, sorting, packing, and cooling.

The completion of harvesting marks the end of the growing season, or the growing cycle for a particular crop, and the social importance of this event makes it the focus of seasonal celebrations such as harvest festivals, found in many cultures and religions.

An edged weapon, or bladed weapon, is a hand-to-hand combat weapon with a cutting edge. Bladed weapons include swords, daggers, knives, and bayonets. Edged weapons are used to cut, hack, or slash; some edged weapons (such as many kinds of swords) may also permit thrusting and stabbing. Edged weapons contrast with blunt weapons such as maces, and with pointed weapons such as spears.

Many edged agricultural tools such as machetes, hatchets, axes, sickles, sling blades, and scythes, have been used as improvised weapons by peasantry, militia, or irregular forces – particularly as an expedient for defence.

The Manstein plan or Case Yellow (German: Fall Gelb; also known after the war as Unternehmen Sichelschnitt a transliteration of the English Operation Sickle Cut), was the war plan of the German armed forces (Wehrmacht) for the Battle of France in 1940. The original invasion plan was an awkward compromise devised by General Franz Halder, the chief of staff of Oberkommando des Heeres (OKH, Army High Command) that satisfied no one. Documents with details of the plan fell into Belgian hands during the Mechelen incident on 10 January 1940 and the plan was revised several times, each giving more emphasis to an attack by Army Group A through the Ardennes, which progressively reduced the offensive by Army Group B through the Low Countries to a diversion.

In the final version of the plan, the main effort of the German invasion was made against the Ardennes, the weakest part of the Allied line, where the defence was left to second-rate French divisions in the Second Army and the Ninth Army, on the assumption that the difficulty of moving masses of men and equipment would give the French plenty of time to send reinforcements if the area was attacked. The Seventh Army, which had been the most powerful part of the French strategic reserve, had been committed to a rush through Belgium to join with the Dutch Army to the north, in the Breda variant of Plan D, the Allied deployment plan.

The Nebra sky disc (German: Himmelsscheibe von Nebra, pronounced [ˈhɪml̩sˌʃaɪbə fɔn ˈneːbra]) is a bronze disc of around 30 cm (12 in) diameter and a weight of 2.2 kg (4.9 lb), having a blue-green patina and inlaid with gold symbols. These symbols are interpreted generally as the Sun or full moon, a lunar crescent, and stars, including a cluster of seven stars, axiomatically interpreted as the Pleiades.

Two golden arcs along the sides (one now missing) are thought to have marked the angle between the solstices. Another arc at the bottom with internal parallel lines is usually interpreted as a solar boat with numerous oars, although some authors have also suggested that it may represent a rainbow, the Aurora Borealis, a comet, or a sickle.
