Context paragraphs:
Major explorations after the Age of Discovery: Major explorations of Earth continued after the Age of Discovery.  By the early seventeenth century, vessels were sufficiently well built and their navigators competent enough to travel to virtually anywhere on the planet by sea.  In the 17th century Dutch explorers such as Willem Jansz and Abel Tasman explored the coasts of Australia.  Spanish expeditions from Peru explored the South Pacific and discovered archipelagos such as Vanuatu and the Pitcairn Islands.  Luis Vaez de Torres chartered the coasts of New Guinea and the Solomon Islands, and discovered the strait that bears his name.  European naval exploration mapped the western and northern coasts of Australia, but the east coast had to wait for over a century.  Eighteenth century British explorer James Cook mapped much of Polynesia and traveled as far as Alaska.  In the later 18th century the Pacific became a focus of renewed interest, with Spanish expeditions, followed by Northern European ones, reaching the coasts of northern British Columbia and Alaska.

Bishop of Thetford: The Bishop of Thetford is an episcopal title which takes its name after the market town of Thetford in Norfolk, England.  The title was originally used by the Normans in the 11th century, and is now used by a Church of England suffragan bishop.

Anglo-Saxons: The Anglo-Saxons were a people who inhabited Great Britain from the 5th century.  They comprise people from Germanic tribes who migrated to the island from continental Europe, their descendants, and indigenous British groups who adopted some aspects of Anglo-Saxon culture and language.  Historically, the Anglo-Saxon period denotes the period in Britain between about 450 and 1066, after their initial settlement and up until the Norman conquest.

Dutch-language literature: Dutch-language literature comprises all writings of literary merit written through the ages in the Dutch language, a language which currently has around 23 million native speakers.  Dutch-language literature is the produce of Netherlands, Belgium, Suriname, the Netherlands Antilles and of formerly Dutch-speaking regions, such as French Flanders, South Africa, and Indonesia.  The Dutch East Indies, as Indonesia was called under Dutch colonization, spawned a separate subsection in Dutch-language literature.  Conversely, Dutch-language literature sometimes was and is produced by people originally from abroad who came to live in Dutch-speaking regions, such as Anne Frank and Kader Abdolah.  In its earliest stages, Dutch-language literature is defined as those pieces of literary merit written in one of the Dutch dialects of the Low Countries.  Before the 17th century, there was no unified standard language; the dialects that are considered Dutch evolved from Old Frankish.  A separate Afrikaans literature started to emerge during the 19th century, and it shares the same literary roots as contemporary Dutch, as Afrikaans evolved from 17th-century Dutch.  The term Dutch literature may either indicate in a narrow sense literature from the Netherlands, or alteratively Dutch-language literature (as it is understood in this article).

Oda of Canterbury: Oda (or Odo; died 958), called the Good or the Severe, was a 10th-century Archbishop of Canterbury in England.  The son of a Danish invader, Oda became Bishop of Ramsbury before 928.  A number of stories were told about his actions both prior to becoming and while a bishop, but few of these incidents are recorded in contemporary accounts.  After being named to Canterbury in 941, Oda was instrumental in crafting royal legislation as well as involved in providing rules for his clergy.  Oda was also involved in the efforts to reform religious life in England.  He died in 958 and legendary tales afterwards were ascribed to him.  Later he came to be regarded as a saint, and a hagiography was written in the late 11th or early 12th century.
