Irciderc in partes reihntes cxrula fila
Fors ferat, in rimas contra rubicunda patentes? ^

Fors ferat at nunquam hoc, ubi fe duo tangere vitra
Frontibus adverfis facies; quia nulla rcfic&i
Fila queant illinc , fed, qua coepta clt via, pergant:
Cu r multa in {olidas nequeant incurrere partes?
Prreterca 1bulla in pingui cur ducitur ordo

Multiplex variufque colorum ? nonne videtur
Undique frons fimilis ? cur hrec jucit, illa colores
Aut hos, aut illos forbet > vel denique nullos?
Pro craifa varie lamella num quoque condet
Partibus in facie varius fitus, atque figura?

Deferat & radios fors tam bene, ut omnibus, uno
Ou i funt in genere , aut rimis tranfmitterc apertis
I l l i c , aut duris incurfibus hic refilirc
Contingat? num lege ulla fors ipfa tenetur?
