Luna die octavo et vicesimo et amplius circiter hora caeli circuitionem percurrens, ex quo signo coeperit ire, ad id signum revertendo perficit lunarem mensem.
The moon runs through its orbit from the sign in which it began, on the twenty-eighth day and about an hour more, and returning to that sign completes the lunar month.
