Do you mean truly legendary, or urban legendary?

I'm interested in this subject too, though as an obligate contact printer I don't quite know *why* I care, given that I could probably get away with using meniscus lenses ground from expired bologna.
Petzvals I think I understand; people seem to use them for shallow DOF with that appealing "swirly" look and a low-contrast "looks like a really old photo" character. But there are other lenses where I know the name but don't know what's special about them.
As one example, what's the big exciting thing about "red dot" Artars?

Hmmm, unique---well on the big buck side are the Pinkham and Smith, the Portland and the Struss. On the relatively cheap side are the Turner-Reich and Wollensak Raptars. In those days every lens grinding company had their own idea of what a lens should do, So we have many different signatures in the rendering of a picture.
So from my perspective all large format lenses are unique
Eh? Wot? Many of them are as the proverbial peas in the proverbial pods.
For example, quality control issues aside, an f/6.3 tessar type is an f/6.3 tessar type is an f/6.3 tessar type. None of them is in any of the lists of legendary lenses I've seen. Best tessar type, perhaps too common.
Lists of legendary lenses can be very strange. For example, include Apo-Artars, exclude Apo-Nikkors (symmetrical type), Apo-Ronars and Repro-Clarons. All peas in a pod. Makes no sense.
Nobody said "legendary" status had to be rational or logical. The mythology benefits those who know better, as it keeps quite excellent lenses off the radar. What is known about the Dagors though is that they do have very substantial image circles for their focal length - not quite Hypergon or Protar, but nonetheless, impressive.
Based on my experience enlarging negatives made by six different Dagors of different focal lengths from 6 to 14 inches, Dagors cover about 65 to 70 degrees, just like your average Plasmat. That huge coverage is one of the legends."Coverage" and "Illumination" are two separate concepts.
