Liminal = occupying a position at, or on both sides of, a boundary or threshold. In mythology, this refers to the meeting of this world and another.
Regarding the painting, I came across a suggestion by the art Moira Huxley that an intriguing effect may be produced by putting a layer of charcoal over an entire watercolour painting and then rubbing out selected parts using a kneadable rubber (= eraser to our American friends). I found the effect delightfully dark, a way of producing almost night-time views.
I have not posted for some time because I developed a sequestrum in my jaw, that being a piece of diseased bone that the body will isolate and then shed. In my case it was in a nasty place where it was lacerating my tongue. A visit to an emergency dentist resulted in the tip of the sequestrum being filed off, which worked for a few days while a visit to a hospital dentistry was arranged by a consultant.
The remainder of the sequestrum, still not ready for my body to shed, was removed last Friday. The pro-seedcake (thank you for that, Winnie) took three dentists and one dental nurse, and took around half an hour. I am now recovering but still spaced out from the anaesthetic. That is not helped by my taking sublingual opioids (Abstral) for pain in my pelvis.
Perusal of the x-ray by both me and the consultant concluded that the sequestrum was in no way related to my cancer, but to a much earlier tooth extraction that left part of the root in place. To my knowledge, that extraction may have been as long as 30 years ago; I cannot recall any other extraction in the area.
My liminal place right now, then, is the junction between my usual self (plus the sublingual opioid) and my current self (now including the after effects of the anaesthetic). I hope you enjoy the artistic result, which includes also some impasto effect in the sky.
