There’s a wonderful article on Minerva Teichert in the Deseret News by Hanna Seariac here:
The article includes several useful links for more information.
Teichert painted several well-known scenes of Book of Mormon events. Although she was influenced by the Mesoamerican theory, her paintings are colorful and imaginative.
The BYU Museum of Art has a collection of her work online. https://moa.byu.edu/minerva-teichert-book-of-mormon-highlights/
Hanna concluded the article with this beautiful passage:
Teichert was a pioneer in Latter-day Saint artwork. She insisted, “I must paint.” She even wrote in her autobiography, “I want … to be able to paint after I leave here. Even though I should come back nine times I still would not have exhausted my supply of subjects and one life time is far too short but may be a schooling for the next.”
