These look as if they were actually ligatures. Without knowing the greek words for the "principal" corners, I'd read them as a rho-omega-kappa, a pi-upsilon, an alpha (delta?)-upsilon-nu-omega and a rho-mu ligature. I wouldn't be surprised, if these letters were abbreviations for some expanded terms for the four principal corners.
On the other hand there do exist ligatures which gained conventional meaning and are now encoded as their own character, eg. ℔, ℅.
