Year 993 ( CMXCIII) was a common year starting on Sunday (link will display the full calendar) of the Julian calendar. Events By place Europe * Spring – The 12-year-old King Otto III gives the Sword of Saints Cosmas and Damian (also known as the Sword of Essen) as a gift to the convent in Essen. It symbolises the martyrdom of Cosmas and Damian, the patron saints of the city. * Charles, duke of Lower Lorraine, dies in prison in Orléans (see 991).

993–994 Carbon-14 Spike
The 993–994 carbon-14 spike was a rapid 0.91% increase in carbon-14 isotope content from tree rings. This event was also confirmed with an associated increase of beryllium-10 in Antarctic ice core samples, supporting the hypothesis that this event was of solar origin. There were several astronomical observations during this time that correspond with the 14C and 10Be spikes, but these texts are few and far between. In 2021, a scientific paper used the 993–994 carbon-14 spike as a benchmark in dendrochronology (tree-ring studies) to precisely determine that Vikings were present in L’Anse aux Meadows in Newfoundland exactly 1000 years prior, in 1021 AD. Historical observations The solar storm hypothesis is heavily supported by several observations of aurora events from late 992 in Korea, Germany and Ireland, usually describing a red sky, presumably due to major auroras. These historical observations don't completely prove the cause of the 993-994 14C spike, but show evidence ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Earth
Earth is the third planet from the Sun and the only astronomical object known to harbor life. While large volumes of water can be found throughout the Solar System, only Earth sustains liquid surface water. About 71% of Earth's surface is made up of the ocean, dwarfing Earth's polar ice, lakes, and rivers. The remaining 29% of Earth's surface is land, consisting of continents and islands. Earth's surface layer is formed of several slowly moving tectonic plates, which interact to produce mountain ranges, volcanoes, and earthquakes. Earth's liquid outer core generates the magnetic field that shapes the magnetosphere of the Earth, deflecting destructive solar winds. The atmosphere of the Earth consists mostly of nitrogen and oxygen. Greenhouse gases in the atmosphere like carbon dioxide (CO2) trap a part of the energy from the Sun close to the surface. Water vapor is widely present in the atmosphere and forms clouds that cover most of the planet. More solar e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dendrochronology
Dendrochronology (or tree-ring dating) is the scientific method of dating tree rings (also called growth rings) to the exact year they were formed. As well as dating them, this can give data for dendroclimatology, the study of climate and atmospheric conditions during different periods in history from wood. Dendrochronology derives from Ancient Greek (), meaning "tree", (), meaning "time", and (), "the study of". Dendrochronology is useful for determining the precise age of samples, especially those that are too recent for radiocarbon dating, which always produces a range rather than an exact date. However, for a precise date of the death of the tree a full sample to the edge is needed, which most trimmed timber will not provide. It also gives data on the timing of events and rates of change in the environment (most prominently climate) and also in wood found in archaeology or works of art and architecture, such as old panel paintings. It is also used as a check in radioc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Essen
Essen (; Latin: ''Assindia'') is the central and, after Dortmund, second-largest city of the Ruhr, the largest urban area in Germany. Its population of makes it the fourth-largest city of North Rhine-Westphalia after Cologne, Düsseldorf and Dortmund, as well as the ninth-largest city of Germany. Essen lies in the larger Rhine-Ruhr Metropolitan Region and is part of the cultural area of Rhineland. Because of its central location in the Ruhr, Essen is often regarded as the Ruhr's "secret capital". Two rivers flow through the city: in the north, the Emscher, the Ruhr area's central river, and in the south, the Ruhr River, which is dammed in Essen to form the Lake Baldeney (''Baldeneysee'') and Lake Kettwig (''Kettwiger See'') reservoirs. The central and northern boroughs of Essen historically belong to the Low German ( Westphalian) language area, and the south of the city to the Low Franconian ( Bergish) area (closely related to Dutch). Essen is seat to several of the region' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Samuel Ibn Naghrillah
Samuel ibn Naghrillah (, ''Sh'muel HaLevi ben Yosef HaNagid''; ''ʾAbū ʾIsḥāq ʾIsmāʿīl bin an-Naghrīlah''), also known as Samuel HaNagid (, ''Shmuel HaNagid'', lit. ''Samuel the Prince'') and Isma’il ibn Naghrilla (born 993; died 1056), was a medieval Jewish Spanish Talmudic scholar, grammarian, philologist, soldier, merchant, politician, and an influential poet who lived in Iberia at the time of the Moorish rule.

Otto III
Otto III (June/July 980 – 23 January 1002) was Holy Roman Emperor from 996 until his death in 1002. A member of the Ottonian dynasty, Otto III was the only son of the Emperor Otto II and his wife Theophanu. Otto III was crowned as King of Germany in 983 at the age of three, shortly after his father's death in Southern Italy while campaigning against the Byzantine Empire and the Emirate of Sicily. Though the nominal ruler of Germany, Otto III's minor status ensured his various regents held power over the Empire. His cousin Henry II, Duke of Bavaria, initially claimed regency over the young king and attempted to seize the throne for himself in 984. When his rebellion failed to gain the support of Germany's aristocracy, Henry II was forced to abandon his claims to the throne and to allow Otto III's mother Theophanu to serve as regent until her death in 991. Otto III was then still a child, so his grandmother, Adelaide of Italy, served as regent until 994. In 996, Otto III ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Majd Al-Dawla
Abu Talib Rustam ( fa, ابو طالب رستم; 997–1029), commonly known by his ''laqab'' (honorific title) of Majd al-Dawla (), was the last ''amir'' (ruler) of the Buyid amirate of Ray from 997 to 1029. He was the eldest son of Fakhr al-Dawla (). A weak ruler, he was a figurehead most of his reign, whilst his mother Sayyida Shirin was the real ruler of the kingdom. Majd al-Dawla's reign saw the gradual shrinking of Buyid holdings in central Iran; Gurgan and Tabaristan had been lost to the Ziyarids in 997, while several of the western towns were seized by the Sallarids of Azerbaijan. There were also internal troubles, such as the revolt of the Daylamite military officer Ibn Fuladh in 1016. Following the death of Sayyida Shirin in 1028, Majd al-Dawla was faced with a revolt by his Daylamite soldiers, and thus requested the assistance of the Ghaznavid ruler Mahmud () in dealing with them. Mahmud came to Ray in 1029, deposed Majd al-Dawla as ruler, and sacked the city, bringi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charles, Duke Of Lower Lorraine
Charles (953 – 22 June 992×995) was the Duke of Lower Lorraine from 977 until his death. Life Born at Reims in the summer of 953, Charles was the son of Louis IV of France and Gerberga of Saxony and the younger brother of King Lothair.

Ulrich Of Augsburg
Ulrich of Augsburg (890 – 4 July 973), sometimes spelled Uodalric or Odalrici, was Prince-Bishopric of Augsburg in Germany. He was the first saint to be canonized not by a local authority but by the Pope. Life Early years Much of the information concerning Ulrich is derived from the ''Life of St Ulrich'' written by Gerhard of Augsburg sometime between 982 and 993. Ulrich was born in 890 at Kyburg, Zurich in present-day Switzerland. He was the son of Hupald, Count of Dillingen (d. 909) and Dietpirch of Swabia (also known as Theoberga).Schmid, Ulrich.

Otto, Duke Of Lower Lorraine
Otto (c. 970–1012) was the duke of Lower Lorraine in Germany from 993 until his death. He was the son of Charles, son of King Louis IV of France, and his first wife, Adelaide of Troyes. When his father left the duchy to fight Hugh Capet for the throne of France in 987, he became regent in Lower Lorraine when still apparently under twenty. Charles was defeated definitively in 991 and died two years later a prisoner in Orléans. Otto then succeeded into the full dukedom. In 1002, at the death of the Holy Roman Emperor Otto III, he was one of the loyal nobles who accompanied his body from Paterno to Aachen. According to the ''Chronica'' of Sigebert de Gembloux, he died in 1006, but he seems to be alive as late as 1012, when Count Godfrey II of Verdun succeeded to the duchy.

Talmud
The Talmud (; he, , Talmūḏ) is the central text of Rabbinic Judaism and the primary source of Jewish religious law ('' halakha'') and Jewish theology. Until the advent of modernity, in nearly all Jewish communities, the Talmud was the centerpiece of Jewish cultural life and was foundational to "all Jewish thought and aspirations", serving also as "the guide for the daily life" of Jews. The term ''Talmud'' normally refers to the collection of writings named specifically the Babylonian Talmud (), although there is also an earlier collection known as the Jerusalem Talmud (). It may also traditionally be called (), a Hebrew abbreviation of , or the "six orders" of the Mishnah. The Talmud has two components: the Mishnah (, 200 CE), a written compendium of the Oral Torah; and the Gemara (, 500 CE), an elucidation of the Mishnah and related Tannaitic writings that often ventures onto other subjects and expounds broadly on the Hebrew Bible. The term "Talmud" may ref ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
