All these images are details of the First picture.
This is in my opinion a picture of the chaotic stage (black background) of the Materia used in the Opus Magnum.
We see the mineral subject, containing the hidden quintaessencia (black 5 pointed star) and also source of the Water of the Sages.
On the left, the antimony symbol containing a little flake, maybe allegorical of the inner Spiritus, Niter, or Mercury it contains. On the left a sphere seemingly representing the Mercury in another form, from the mineral suject.
