I have made an improved version about the Ezelius adjustable knots with better images and with the text edited on this page:
http://ezelius.eu/knopar/ezeliusknop/en.html
Any suggestions to improve the text are welcome.
The Ezelius hitch is interesting in its 2 corresponding forms.
[ ] In your first set of images - it is presented in noose form.
[ ] In the the second set of images, it is presented as a slide and grip progression hitch.
Note the correspondence between the two hitches.
In
noose form, the SPart is its own 'host' and there is an adjustable eye.
In
slide and grip progression form, an independent 'host' is required - and there is no adjustable eye.
The loading profile is different in both cases.
In noose form, the hitching component only has 50% load.
In slide and grip progression form, the hitching component has 100% load.
It is noticeable when the leg of the hitch is loaded - since it causes greater distortion in the hitching structure.
...
Overall, a nice effort.
I must say that the
Gnat hitch presented by roo some time ago is quite a remarkable hitch in its own right.

https://notableknotindex.webs.com/gnathitch.html On this website, it is presented in
noose form.
The Gnat hitch also has a
corresponding slide and grip progression form (not shown).
Its a very
efficient structure - requiring minimal rope to form the hitch.
It also has considerable grip strength - particularly in slide and grip progression form (because 100% load is directed to the hitching component.
In noose form, only 50% is directed to the hitching component.
I have been investigating if the Gnat hitch could be useful in surgical applications - which I think is worthy of follow up study. Surgeons are looking for new and improved hitches - and the Gnat hitch might be a promising alternative.
I have also been actively promoting the Gnat hitch (in noose form) as a foot stirrup used with a 'jumar' (ie mechanical ascender) for rope access technicians.
