After the release of my book De hoeve en het hart (The Homestead and the Heart, about a family of farmers in the Dutch Golden Age), I got many questions about the Roosa family.
Now, my book is about the Roosa’s indeed, but it’s not a genealogical study. You could call it an example of microhistory: it describes the mentality and culture of farmers in the Dutch province of Guelders in the early modern period (1600-1750).
Nevertheless, I got a lot of genealogical questions: ‘Did you know that Gijsbert Goertsen’s father was Goert Reijersen’ or ‘Why do you think Gijsbert Goertsen’s father was not Goert Reijersen?’
In my book there was only room in the footnotes to explain a few things – that’s why I thought it would probably be best to clarify the matter in a seperate article on my website.
In my opinion, the Roosa family is not related to Goert Reijersen, Jutte van Heukelum, Jutte van Culemborg and Arnt van Rosendaell – you’ll find my arguments here.

Life after Revius: no more Latin, no more intellectual debates on predestination and cartesianism. I’m now busy studying a seventeenth-century farmer’s family in the Dutch province of Guelders.
It’s all caused by Arien van Rijckhuijsen (1671-1750), a farmer from the village of Herwijnen. Maybe he lived a rather unremarkable life, nearly eighty years on the same farm, in the same village. But as a person, he stands out because he was a writing farmer. He loved telling family stories, and as his son lived in the city of Leiden, he wrote many letters on the subject.
These letters have survived three centuries, and now they are a rather unique historical source, telling the story of a farmer family in the seventeenth and eighteenth centuries from an inside perspective.
It’s what I’m going to write about in my new book.
Though that will take some time yet.

While listing the reviews of my Revius-biography, I noticed something remarkable. Nearly all reviewers  deal with the question: Is the reformed background of the biographer getting in her way? Does she manage to keep her distance, in spite of her emphatic attitude? I’m glad to see that most of them think it’s OK with me and Revius, although in one case there remains some doubt.
Yet, a biographer feeling affinity with the protagonist seems to me something totally unremarkable, maybe even inevitable.  Hermione Lee on Virginia Woolf, Elsbeth Etty on Henriette Roland Holst, Steven Nadler on Spinoza, Michel van der Plas on Godfried Bomans, etcetera. The only thing a biographer needs, is a thorough awareness of the particular risks of empathy, while consciously employing the benefits of it.
Maybe it’s because the traditional ‘reformed biography’ (aiming frankly at strengthening the religious identity of reformed protestants ) always had quite a reputation? I think I’m going to write about this, sometime.

It’s still possible to find unknown poems of the great poets from the Dutch Golden Age, if you know where to look. While I was researching the life and work of Jacob Revius, I discovered (sometimes with the help of others) 19 unknown poems, 8 letters, 2 manuscripts with collected letters, poems and quotes, and a document containing some speeches Revius delivered as a student.
But new discoveries can also be made in well-known texts. Everybody knows such texts exist, but nobody takes the trouble to find and read them – because they’re written in Latin, or because they can only be consulted in foreign libraries.
That’s the reason why I decided to publish all literary texts that cannot simply be found in Revius’ verse collection Over-Ysselsche sangen en dichten on this website. But I’m never going to do the same with the theological texts – just consider the fact that he published more than 13.000 pages during his lifetime…

Sometimes I’m thinking Revius would have been very happy with the internet. Just a quick browse to see how the Prince and his army were getting on in the Dutch-Spanish war… Not to mention the overwhelming richness of classical texts, available by just pressing a few buttons.
But he would have been embarrassed with facebook and twitter. He didn’t like the exhibition of personal details, even in his poems.
Which makes him a rather challenging person for a biography.
I remember Margaretha Schenkeveld saying that a writer’s biography needs to show in which way the author distilled the ‘gin of poetry’ from the ‘grain of life’.
This is much more difficult than you’d think.
But thanks to a unique letter from the seventeenth century, we’re able to exactly follow the distillation process  in one of Revius’s poems.
That story is told in my article ‘De vingerafdruk van de dichter’, published in the newest issue of the literary magazine Liter.
The (Dutch) text can be read here.

Johannes Maurus was the first Dutch-Moroccan Calvinist.
I came across his name in Jesus College Library, Oxford, where his five disputations on Islam are kept. 
These texts made me wonder about his life.
How could it be that, somewhere between 1640 en 1643, a Moslem from Morocco settled in the Dutch Republic, got converted to Christianity and even embarked on a study in reformed theology? And why was he anxious to inform his fellow students about Islam?
The newest issue of Tijdschrift voor Nederlandse kerkgeschiedenis (december 2010) contains my account of Maurus’s life and his unsuccessful efforts. The (Dutch) text of this article, ‘Een Marokkaan in het Statencollege’, can be read here.
Maybe Maurus will be the subject of my next project.
