Aga, there are several species that look very similar to that. They are all ground-spreading plants. They all have the same shaped leaves. They all have the little dots of pinkish flowers at the leaf nodes. The only difference between them is the arrangement of the little dot flowers, and since they didn't draw this detail well enough in medieval drawings, one cannot be sure which one it is without a label.
In my opinion. the VMS drawing of this group of plants is more accurate, but I would be careful about comparing it to other plant books of the time (they are less accurate).
Possibilities include Polygonum aviculare, Peplis portula, Ammannia baccifera, Euphorbia maculata, Euphorbia prostrata, Euphorbia thymifolia (maybe, or this may be VMS f4r), and a few others that are less common. Here are two that I particularly like:
