Una congettura a Lucr. 6,623

In Lucretius' De rerum natura 6,623 f., a textual corruption has caused the repetition of the word venti in two consecutive lines. Most editors accept Cippellarius' emendation of the second venti (l. 624) to ventis, namely a causal ablative belonging to the following proposition; nevertheless, in this case the order verborum would be strange. Others prefer ponti, a humanistic conjecture, which destroys the expressive alliteration in the second hemistich of the line. By comparing this passage with Lucr. 5,266 and 5,388, I suggest that the second venti is genuine, proposing to emend the first one (l. 623) to summa, which must be referred to umorismo.
