The top picture is Benjamin's description of Plate I.
Plate I is below.
Asher Benjamin is the only writer I know of who discusses why to use one molding instead of another. I have added some comments.
" The ovolo and ogee, being strong in their extremities are fit for supports; the cimarecta and cavetto, though improper for that purpose, as they are weak in the extreme parts, and terminate in a point, are well contrived for coverings to shelter other members;"*
I love that he asked me, the reader, to see if a molding seems to convey a feeling of strength or shelter. It's only a shape - a bit of trim casting a shadow, if there's enough light.
"... the tendency of their outline being very opposite to the direction of falling water, which, for that reason, cannot glide along their surface, but must necessarily drop." *
This last piece of his sentence is one reason I think Benjamin's books were so successful. Not only was he explaining to the carpenter how to think about how a specific molding would communicate an idea, a sense of a building's character, he was reminding the reader of the basic problem of construction: keeping water away.
Asher Benjamin doesn't forget the important stuff: Successful buildings need to do everything at once: delighting the eye while also keeping us dry and comfortable.
