Geometric construction of uppercase Roman letters

I am looking for treatises from the 15th and 16th centuries that provide instructions for geometrically constructing the capital letters of the alphabet. I have found these sources.
Do you have any suggestions on where to find more information?

    I know that it does not reflect reality and it is an idealizing reinterpretation widespread in the Renaissance, but I am only interested in comparing these reinterpretations  :)
