Columns, Specs by Vitruvius

I read Vitruvius' De Architectura (or should that be Vitruviorum De Architectura) a long time ago. One of the sections of the book is the proper proportions and spacings of columns. The above illustration is from a 1914 translation. After reading this book you notice buildings with "classical" accents that look wrong, with columns too thin, too widely spaced. I am aware that the look of Greco-Roman classical architecture was a result of limitations of building technologies and material science.
