Arnold write books and articles about old manuscripts. This way these manuscripts become more accessible. He usually works from behind his desk. In summer he works under an olive tree in Greece.
Arnold doesn’t need his ears to work. He does most of his work alone, and he communicates mostly via email. Which is fortunate, because he’s turning deaf.
He did the same work he does today long before personal computers existed. He used quite a lot of paper, and ink for his typewriter. And he had all kinds of paper archives. And envelopes for his letters to his colleagues. Now he uses a computer.
Arnold doesn’t need his mouth to smile. He smiles with his eyes. And he needs his eyes for working. For using his lexicons, for using his computer, for everything, really.
Arnold doesn’t use his feet for his actual work.
Arnold need his hands for making his books and his articles. He types them. And he needs them to use his (paper) lexicons, and and to search for things in other books.
Arnold makes good use of his head. He thinks with it quite a lot. He talks with it, he listens with it (with the help of a hearing aid), he looks with it, he smiles with it.
This is where Arnold works when he’s not spending the summer in Greece. A flashing phone (he doesn’t hear it ringing), books, paper for notes, some pens and always an orange.
These old fashioned paper lexicons are Arnold’s tools. These are the lexicons to his left. He has another row of these on the right.
These manuscripts are inaccessible. By publishing them with current letters, and by adding a commentary to them more people can read them. Is that the only reason why? Probably not. He absolutely loves his work, and the manuscripts he works with. It’s much more than just a service to humanity.
