It means no to cross the line. I hope this helps you :]
The sentence whose style is most appropriate with respect to clarity and simplicity of language is the first one - For centuries, art admirers have been digging through records of the painting to figure out its meaning.
The other sentences use language that is quite complicated.
Faustus was sinful
sinning is thematic throughout Faustus!!
Dear Diary,
October 31st, 1658
On this very day, I survived a kraken attack. We were on our ship, and we had to bring ammunition's to other country's. T was very stormy on he high seas, but we managed. Later in the trip I saw something in the water, like a tentacle? I warned that captain but he ignored it. Eventually we heard a loud boom from underneath the ship, water started to get in! The captain shouted " Kraken!" Everyone started to panic. I decided to grab a spear, gather some spar wood and rope; to make a raft. The I'd use the spear to stab the kraken in the eye on my way to safety. I tied the last rope, and made my way toward the kraken.......
I made it to the kraken, i very slowly and carefully stabbed the kraken! She let out a huge roar before smashing the ship to pieces! I was very lucky to have gotten away.
