The book’s full title lists all the subjects, working fields and parts of history it covers with it’s contents as a dictionary. It is supposed to speak to all kinds of architects but might also speak to an “ordinary person” or a layman who wants to study general definitions of things found in one’s daily life. The book does not contain a list of contents since it’s alphabetically structured (as any dictionary), but there is an “avertissement” or in English “warning” for the book of 6 pages. It explains why this dictionary was written for example that one can’t handle material and structure the way it’s supposed to without understanding the basic definition of it. There are no illustrations inside the book since it’s a dictionary over many topics, not only explaining one by going into detail. The book is rather thick but not very large in format. I’m guessing it was supposed to be handy and one should be able to carry it around in case clarification is needed. Alexandre le Blond wrote this dictionary in Paris in 1710 hoping it would help not only architects in understanding their design but also mathematicians, mechanics, artists such as painters or sculptors, even musicians and many more. This shows how these fields melt into each other, even though some words might not have the same meaning in all of them. You could say architecture, in my interpretation of le Blond, isn’t only buildings and streets, but musicians, engineers, mathematicians artists and many more are architects in their own way. Architecture is a form of art, and so are many other things.
