Ferrous metallurgy is the metallurgy of iron and its alloys.
 It began far back in prehistory.
 The earliest surviving iron artifacts, from the 4th millennium BC in Egypt, were made from meteoritic iron-nickel.
 It is not known when or where the smelting of iron from ores began, but by the end of the 2nd millennium BC iron was being produced from iron ores from China to Sub-Saharan Africa.
 The use of wrought iron (worked iron) was known by the 1st millennium BC, and its spread marked the Iron Age.
 During the medieval period, means were found in Europe of producing wrought iron from cast iron (in this context known as pig iron) using finery forges. For all these processes, charcoal was required as fuel.
The Nordic Bronze Age (also Northern Bronze Age, or Scandinavian Bronze Age) is a period of Scandinavian prehistory from c. 1700–500 BC.
 The Bronze Age culture of this era succeeded the Nordic Stone Age culture (Late Neolithic) and was followed by the Pre-Roman Iron Age.
 The archaeological legacy of the Nordic Bronze Age culture is rich, but the ethnic and linguistic affinities of it are unknown, in the absence of written sources.
 Some scholars also include sites in what is now Estonia, northern Germany and Pomerania, as part of its cultural sphere.
Danish art is the visual arts produced in Denmark or by Danish artists.
 It goes back thousands of years with significant artifacts from the 2nd millennium BC, such as the Trundholm sun chariot.
 For many early periods, it is usually considered as part of the wider Nordic art of Scandinavia.
 Art from what is today Denmark forms part of the art of the Nordic Bronze Age, and then Norse and Viking art.
 Danish medieval painting is almost entirely known from church frescos such as those from the 16th-century artist known as the Elmelunde Master.
Karakol culture (Turkic "Black lake") is a Bronze Age archaeological culture of the 2nd millennium BCE in the Altai area, contemporaneous with the Afanasiev culture.
 Karakol culture was discovered in 1985 near village of Karakol in Altai.
 In the Altai territory, the Bronze Age extended from the 3rd to the 2nd millennium BCE, bronze was a main material for tools, weapons and jewelry.
 At that time in the Altai territory lived people of the Karakol and Afanasiev cultures.
 Most of the investigated Karakol culture burials are located on the banks of the river Ursul and its tributaries.
The history of Ankara can be traced back to the Bronze Age Hatti civilization, which was succeeded in the 2nd millennium BC by the Hittites, in the 10th century BC by the Phrygians, and later by the Lydians, Persians, Macedonians, Galatians, Romans, Byzantines, Seljuks, and Ottomans.
The Trundholm sun chariot (Danish: "Solvognen" ), is a Nordic Bronze Age artifact discovered in Denmark.
 It is a representation of the sun chariot, a bronze statue of a horse and a large bronze disk, which are placed on a device with spoked wheels.
The Ochre Coloured Pottery culture (OCP) is a 2nd millennium BC Bronze Age culture of the Indo-Gangetic Plain (Ganges-Yamuna plain).
 It is a contemporary of and successor to the Indus Valley Civilization.
 The OCP marked the last stage of the North Indian Bronze Age and was succeeded by the Iron Age black and red ware culture and the painted gray ware culture.
 Early specimens of the characteristic ceramics found near Jodhpura, Rajasthan, date from the 3rd millennium (this Jodhpura is located in the district of Jaipur and should not be confused with the city of Jodhpur).
 Several sites of culture flourish along the banks of Sahibi River and its tributaries such as Krishnavati river and Soti river, all originating from the Aravalli range and flowing from south to north-east direction towards Yamuna before disappearing in Mahendragarh district of Haryana.
The Alepotrypa Cave is an archaeological site in the Mani region of the Peloponnese peninsula.
 In addition to being inhabited by early farmers, this site was used for burial and cultic purposes.
 Archaeological evidence has revealed that this is one of the largest Neolithic burial sites that has ever been found in Europe.
 While settlement in the southern Laconia region usually dates as far back as the Early Bronze Age, archaeological evidence has shown that the Alepotrypa site was inhabited during the Neolithic period.
 Two adult human skeletons were found at the site from a burial dating to the 4th century BC, and remains from at least 170 separate persons have been found.
 Non-lethal wounds found on skulls from the cave suggest that this period was particularly violent.
 Archaeologists are uncertain about the significance of a Mycenaen ossuary, which as been dated to the 2nd millennium BC.
 The lead excavator at the site Giorgos Papathanassopoulos has suggested that the ossuary may provide a link between Neolithic burial practices and the Classical era.
The 2nd millennium BC spans the years 2000 through 1000 BC.
 It marks the transition from the Middle to the Late Bronze Age.
