Mother of monsters

Cynthia, quite literally, gave birth to the Teratagenic Art Movement.
She’d get pregnant and then take a whole series of birth defects-causing chemicals.
Once the “artwork” was ready, she’d have a late-term abortion and have the monstrosity preserved in a jar.
She was quite a prolific artist, splashing life and death on her revolting canvases.
When menopause finally hit, she realized that she had birthed no heir to pass her craft to.
Nor would any right-minded agency allow her to adopt.
Students came and students went, but the chemicals eventually killed Cynthia.
And the Art Movement with her, thank God.
