In 2001 Sebastian Adorján Dyhr wrote his M.A. thesis ‘Grammatik over det creolske sprog’ af Joachim Melchior Magens I en lingvistisk og historisk kontekst (Aarhus Univeritet, supervisor: Peter Bakker). This thesis is an extensive description of this first published Creole Grammar and its author. I am very grateful to Dyhr for giving permission to make it available on my website.
Not only his description of the grammar is of interest. Dyhr discovered the original ‘Magens’ letter which was published by Schuchardt and commented on by Hesseling in Tijdschrift voor Nederlandse Taal- en Letterkunde (1914). This letter is the only example of Virgin Islands Dutch Creole from the end of the nineteenth century, a period in which this language was thought to have been extinct. This appendix is however only available on request.
The thesis can be found on the Scanned publications page
