In about 1966/7, when I was managing the small 'Fine Art Gallery' in London's Devonshire St W1, I met a lady who's name was Marevna. Just by chance I was recently looking at a self-portrait by someone called Marevna; and I put two and two together!
I'm certain that she'd said she had been the wife of Diego Rivera. We had conversed in French, so I may well have misunderstood the meaning of 'femme'
However, she was a fascinating and ebullient woman, and we spent several pleasant hours together over a period of several weeks, after which she invited me to stay at some estate in Mexico, where visiting painters were lodged in small cottages and got together in the evenings to discuss 'artistic things'.
Thanks to Wiki, I now discover that she had in fact been the 'mistress' of Rivera, and had a daughter by him.
Marie (Marevna) Bronislava-Stebelska had lived in Paris, where she met Rivera, then later in London (where I met her).
Goodness knows why she invited me to stay at Diego's estate in Mexico; I had absolutely no intention of going, and I don't suppose she had any right to invite me. Both Rivera and Kahlo were deceased by that time, and I have no idea what connection she had with his estate.
Discovering her self-portrait recently (above) brought it all back, and I remembered her well. She was much older when I met her, plumper, and more 'matronly' looking than in the self-portrait. I also remember her name as being Mar-ee-evna; now I know differently.
I wish Wiki had been around at the time; if I'd known her interesting history I would have delved!
