Huc accedit ut in summa res nulla sit una,
unica quae gignatur et unica solaque crescat,
quin aliquoiu' siet saecli permultaque eodem
So it follows that in the whole [of everything] no single thing would exist
that all alone would be born and all alone would thrive
but-instead each-thing would be of-some-kind and very many
would belong to each kind. [of each kind there would be many instances]
1. help me with the verb "siet". What is its dictionary headword?
2. does "aliquoiu'" = "aliquoius" = "alicuius"?
3. I am guessing about the passage that starts "quin...". Please parse this for me.
