The Middle Kingdom of Egypt (also known as The Period of Reunification) is the period in the history of ancient Egypt between circa 2050 BC and 1800 BC, stretching from the reunification of Egypt under the impulse of Mentuhotep II of the Eleventh Dynasty to the end of the Twelfth Dynasty.
 Some scholars also include the Thirteenth Dynasty of Egypt wholly into this period as well, in which case the Middle Kingdom would finish c. 1650, while others only include it until Merneferre Ay c. 1700 BC, last king of this dynasty to be attested in both Upper and Lower Egypt.
 During the Middle Kingdom period, Osiris became the most important deity in popular religion.
Harageh (also el-Harageh or Haraga) is a modern village in Egypt at the entrance to the river oasis of the Fayum, close to El-Lahun.
 In archaeology Harageh is mainly known for a series of cemeteries dating to several periods of Egyptian history.
 Reginald Engelbach excavated these cemeteries in 1913.
 The cemeteries belong to the Naqada-Period, to the First Intermediate Period, to the late Middle Kingdom and to the New Kingdom, a few Coptic stelae were discovered too.
 Especially the burials of the late Middle Kingdom belonged to wealthy people.
 Perhaps the people of El-Lahun were buried here.
 Engelbach found stelae, inscribed coffins, canopic boxes and jars and many statues.
Stone weights from the Old Kingdom have been found, weighing about 13.6 grams. Similar weights from the Middle Kingdom were discovered at Lisht.
 From the Middle Kingdom date also "deben" weight units used for metals, referred to as copper deben and gold deben, the former being about twice as heavy (c. 23.7 grams) as the latter.
Night Mail is a 1936 documentary film about a London, Midland and Scottish Railway (LMS) mail train from London to Scotland, produced by the GPO Film Unit.
 The film ends with a "verse commentary" by W. H. Auden, written for existing footage.
 Benjamin Britten scored the film.
 The film was directed by Harry Watt and Basil Wright, and narrated by John Grierson and Stuart Legg.
 The Brazilian filmmaker Alberto Cavalcanti was sound director.
 The locomotive featured in the film was Royal Scot 6115 "Scots Guardsman", built in 1927.
 The film has become a classic of its own kind, much imitated by adverts and modern film shorts.
 "Night Mail" is widely considered a masterpiece of the British Documentary Film Movement.
Ameny was an Ancient Egyptian vizier under Middle Kingdom king Amenemhat II, around 1900 BC, in the Twelfth Dynasty.
 Ameny appears on the fragment of an annal stone of the king.
 The fragment was found by Flinders Petrie in Memphis and mentions a statue of this vizier.
 Ameny is perhaps also known from an offering table.
 However, the name Ameny belongs to the most common names of the Middle Kingdom.
 Therefore, the identity of both people on these objects is far from certain.
A pyramidion (plural pyramidia) is the uppermost piece or capstone of an Egyptian pyramid or obelisk, in archaeological parlance.
 They were called "benbenet" in the Ancient Egyptian language, which associated the pyramid as a whole with the sacred benben stone.
 During Egypt's Old Kingdom, pyramidia were generally made of diorite, granite, or fine limestone, which were then covered in gold or electrum; during the Middle Kingdom and through the end of the pyramid-building era, they were built from granite.
 A pyramidion was "covered in gold leaf to reflect the rays of the sun"; during Egypt's Middle Kingdom, they were often "inscribed with royal titles and religious symbols."
Rifeh or Deir Rifeh (also known as Rifa) is a village in Egypt.
 The name refers today most often to a series of Ancient Egyptian cemeteries nearby.
 These are the burial grounds of the ancient town Shashotep.
 The cemeteries date from the end of the First Intermediate Period to the Roman Period.
 Especially important are the burials of the Middle Kingdom.
 In this period Shashotep was the capital of the 11th Upper Egyptian province.
 Several decorated rock cut tombs were carved into the rocky hills.
 They belong to the local governors of the period.
 Nakht-Khnum and Nefer-Khnum are the two whose names survived.
 In front of these tombs were burials of lower officials that were working for these local governors.
 One of them is the Tomb of two Brothers, that was found undisturbed and still contained an array of important artcfacts.
 Further away and closer to the Nile were the burials of the more common people.
 Typical for many of these burials dating to the Middle Kingdom model clay houses, once placed on top of the burial.
 They are called in Egyptology "soul houses".
 Further burials belong to the Second Intermediate Period and to the New Kingdom, when Shashotep was no longer the capital of a province.
Night Mail is a 1935 British film.
 It is not to be confused with the 1936 documentary "Night Mail".
Maaibre Sheshi (also Sheshy) was a ruler of areas of Egypt during the Second Intermediate Period.
 The dynasty, chronological position, duration and extent of his reign are uncertain and subject to ongoing debate.
 The difficulty of identification is mirrored by problems in determining events from the end of the Middle Kingdom to the arrival of the Hyksos in Egypt.
 Nonetheless, Sheshi is, in terms of the number of artefacts attributed to him, the best attested king of the period spanning the end of the Middle Kingdom and the Second Intermediate period; roughly from c. 1800 BC until 1550 BC.
 Hundreds of scaraboid seals bearing his name have been found throughout Canaan, Egypt, Nubia and as far away as Carthage where some were still in use 1500 years after his death.
Round Eyes in the Middle Kingdom is a 1995 documentary directed by Ronald Levaco, an American filmmaker who journeyed back to China, the nation of his boyhood days, to discover what became of an old friend of his family, Israel Epstein.
