Esto rhombus ex conis æqui-
cruribus compositus .
secetur unus conorum plana
superficie quæ basi æqui-
distans sit et sit sectio .
A circulo cuius diameter
erigatur conus cuius vertex .
et factus est rhombus .
sit perpendicularis
ad productam
[Translation: Let this rhombus be composed from equal-sided cones. Let one of the cones be cut by a plane surface which is equidistant from the base ad let the section be . From the circle whose diameter let there be erected a cone whose vertex is , and make the rhombus . Let be perpendicular to produced.

Dico quod: si a rhombo
abstruhatur rhombus :
resliquum solidum erit,
æquale cono
[Translation: I say that, if from the rhombus there is taken away the rhombus , the remaining solid will equal to the cone .
