Context paragraphs:
The Garden Tomb: The Garden Tomb is a rock-cut tomb in Jerusalem which was unearthed in 1867 and has been considered by some Protestant Christians to be the site of the burial and resurrection of Jesus though the tomb has been dated by prominent Israeli archaeologist Gabriel Barkay to the 8th-7th centuries BC, making it unlikely that it could actually be the tomb of Jesus.  There is no reason, however, for an older tomb not having been reused later on, as it was not an uncommon practice.  The Garden Tomb is adjacent to a rocky escarpment which since the mid-nineteenth century has been proposed by some scholars to be Golgotha.  In contradistinction to this modern identification, the traditional site where the death and resurrection of Christ are believed to have occurred has been the Church of the Holy Sepulchre at least since the fourth century.

Odzun Church: Odzun Church (Armenian: Օձունի եկեղեցի ) is an Armenian basilica constructed around the 5th-7th century in the Odzun village of the Lori Province of Armenia.

Hymettus: Hymettus ( ), also Hymettos ( ; Greek: Υμηττός , transliterated "Ymīttós", pronounced ] ), is a mountain range in the Athens area of Attica, East Central Greece.  It is also colloquially known as "Trellós" (crazy) or "Trellóvouno" (crazy mountain); the latter originates from the French "très long" (very long) in awe of its winding length of 16km, as used by French travelers during the occupation of Greece by the Ottomans.  In antiquity there was a sanctuary to "Zeus Ombrios" (Zeus the Rain God) on the summit with numerous offerings dating especially to the 8th-7th centuries BC; they are on the site of a military base and not currently accessible.  There is also an ancient quarryman's hut on the western slopes of the mountain, one of two buildings in ancient Attica which preserves its roof.

Martynivka Treasure: Martynivka Treasure (Ukrainian: Мартинівський скарб , "Martynivsky skarb") is a hoard consisting of 116 silver items (weighing about 3.3 kg) found in 1909, in the village of Martynivka, Cherkasy Oblast, Ukraine.  The treasure is currently preserved at the National Historical Museum of Ukraine in Kiev and the British Museum in London.  It is dated approximately to the 6th-7th centuries AD.

Shetland Scots: Shetlandic, usually referred to as ("auld" or "braid") "Shetland" by native speakers, and referred to as Modern Shetlandic Scots (MSS) by linguists, is spoken in Shetland, to the north of mainland Scotland and is, like Orcadian, a dialect of Insular Scots.  It is derived from the Scots dialects brought to Shetland from the end of the fifteenth century by Lowland Scots, mainly from Fife and Lothian, with a degree of Norwegian influence from the Norn language, which is an extinct North Germanic language spoken on the islands until the late 18th century.

Dacology: Dacology is a branch of Thracology which focuses on the scientific study of Dacia and Dacian antiquities and is a regional and thematic branch of the larger disciplines of ancient history and archaeology.  A practitioner of the discipline is a Dacologist.  Dacology investigates the range of ancient Dacian culture (language, literature, history, religion, art, economics, and ethics) from c. 1000 BC up to the end of Roman rule in the 4th-7th centuries.  It is directly subordinated to Thracology, since Dacians are considered a branch of the Thracians by most mainstream research and historical sources.  Other theories sustain that the Daco-Thracian relation is not as strong as originally thought and as such Dacology has the potential to evolve as an independent discipline from Thracology.

Courbillac: Courbillac is a commune in the Charente department in southwestern France.  In 1886, Philippe Delamain, a merchant from Jarnac, discovered by chance a cemetery from the Merovingian period in Herpes near Courbillac.  He found an outstanding collection of weapons, brooches, jewellery and vases dating from the time when the Franks had settled in Herpes (5th-7th centuries AD).  His collection was dispersed soon after its discovery but a significant proportion is in the British Museum, London.

Jvari inscriptions: The Jvari inscriptions (Georgian: ჯვრის წარწერები ) are the Georgian language inscriptions written in the Georgian "Asomtavruli" script on the Jvari Monastery, a basilica located near Mtskheta, Georgia.  The inscriptions mention Georgian princes Stephen I of Iberia, Demetrius the Hypatos and Adarnase I of Iberia.  However, Professor Cyril Toumanoff disagrees with this view and identifies these individuals with Stephen II of Iberia, Demetrius and Adarnase II of Iberia, respectively.  Inscriptions are dated to the 6th-7th centuries.

History of English: English is a West Germanic language that originated from Anglo-Frisian dialects brought to Britain in the mid 5th to 7th centuries AD by Germanic invaders and settlers from what is now northwest Germany, west Denmark and the Netherlands, displacing the Celtic languages that previously predominated.
