There I met David Thomas, a compact, cheerful, softspoken man with gray hair, the senior archivist. When I arrived, Thomas was hefting a large, ungainly bound mass of documents-an Exchequer memoranda roll from the Hilary (or winter) term of 1570-onto a long table in his office. A thousand pages of sheepskin parchment, loosely bound and with no two sheets quite matching, it was an unwieldy load requiring both arms to carry. “In some ways the records are extremely good,” Thomas told me. “Sheepskin is a marvelously durable medium, though it has to be treated with some care. Whereas ink soaks into the fibers on paper, on sheepskin it stays on the surface, rather like chalk on a blackboard, and so can be rubbed away comparatively easily.

“Sixteenth-century paper was of good quality, too,” he went on. “It was made of rags and was virtually acid free, so it has lasted very well.”

To my untrained eye, however, the ink had faded to an illegible watery faintness, and the script was of a type that was effectively indecipherable. Moreover the writing on the sheets was not organized in any way that aided the searching eye. Paper and parchment were expensive, so no space was wasted. There were no gaps between paragraphs-indeed, no paragraphs. Where one entry ended, another immediately began, without numbers or headings to identify or separate one case from another. It would be hard to imagine less scannable text. To determine whether a particular volume contained a reference to any one person or event, you would have to read essentially every word-and that isn’t always easy even for experts like Thomas because handwriting at the time was extremely variable.

Elizabethans were as free with their handwriting as they were with their spelling. Handbooks of handwriting suggested up to twenty different-often very different-ways of shaping particular letters.
