I learned about this from Margaret Daly Davis's book "Piero Della Francesca's Mathematical Treatises: The Trattato D'abaco and Libellus de Quinque Corporibus Regularibus" (1977).
Della Francesca is of course more famous as a painter than a mathematician. His book was famously plagiarized by Luca Pacioli's 1509 "Divina proportione", illustrated by da Vinci. I think maybe this includes the material on domes.
