Over Time

The focus of this chapter is on how languages move and change over time and space. The perceptions of historical linguists have been shaped by what they were observing. During the flowering of comparative linguistics, from the late 19th into the 20th century, the dominant view was that in earlier times when people moved, their languages moved with them, often over long distances, sometimes fast, and that language change was largely internal. That changed in the second half of the 20th century. We now recognize that in recent centuries and millennia, most movements of communities and individuals have been local and shorter. Constant contact between communities resulted in features flowing across language boundaries, especially in crowded and long-settled locations such as most of Central and West Africa. Although communities did mix and people did cross borders, it became clear that language and linguistic features could also move without communities moving.

COVID-19 is affecting Christian mission in many different ways. Doubtless it is inspiring some people to initiate new mission efforts, while in other contexts it is causing thriving mission to change radically or cease altogether. In this forum article, three missiologists write essays about how mission was affected during the influenza pandemic of 1918–1919, the event most frequently compared to COVID-19 for its similarly worldwide scope. James Krabill’s essay describes how the earlier influenza pandemic led to renewed spiritual vigor in Nigeria and the establishment of several new denominations in West Africa, which remain influential today. Robert Danielson’s essay examines how a ministry to sailors in the early 20th century, known as the Floating Christian Endeavor, was negatively impacted by the influenza pandemic. This article concludes with Benjamin Hartley’s story of how the life of John R Mott, perhaps the most famous world Christian statesman in 1918, was also affected by the influenza’s scourge. These historical essays provide both inspiration and consolation for contemporary mission initiatives as missiologists and other Christian leaders seek to respond to the crises of their own day.

Onchocerciasis, also known as River Blindness, is a parasitic disease caused by the nematode Onchocerca volvulus and transmitted by black flies of the genus Simulium. It is endemic in Africa, where an estimated 37 million people are infected. It is almost certain that the slave trade in the 17th and 18th centuries brought onchocerciasis from West Africa to the Americas (1), where transmission foci where established in six countries: Mexico, Guatemala, Venezuela, Brazil, Ecuador and Colombia. Since the beginning of the 20th century it was suspected that this vector borne disease was present in Colombia but the first confirmed case was not reported until 1965. The exact location of the single focus in the country was confirmed almost thirty years later in the locality of Naicioná, on the stream that bears the same name

The Subject

Literatures concerning the history of West African peoples published from 1900 to 1970 debate�the possible migrations of the Egyptians into West Africa. Writers like Samuel Johnson and�Lucas Olumide believe that the ancient Egyptians penetrated through ancient Nigeria but Leo�Frobenius and Geoffrey Parrinder frowned at this opinion. Using the works of these early�20th century writers of West African history together with a Yoruba legend which teaches�about the origin of their earliest ancestor(s), this researcher investigates the theories that the�ancient Egyptians had contact with the ancient Nigerians and particularly with the Yorubas.Intradisciplinary and/or interdisciplinary implications: There is an existing ideology�amongst the Yorubas and other writers of Yoruba history that the original ancestors of�the Yorubas originated in ancient Egypt hence there was migration between Egypt and�Yorubaland. This researcher contends that even if there was migration between Egypt and�Nigeria, such migration did not take place during the predynastic and dynastic period as�speculated by some scholars. The subject is open for further research.
