I can't count the times I've researched a building only to find no one bothered to write down even the name of an architect, let alone the name of the builders. That they even named a laborer working on the project is great; the kind of detail in that note is extremely rare. Definitely more interesting to me as a historian than finding a poem about blazing a light through the darkness to guide lost sailors or something (not that that wouldn't be neat too).
