¨Arranged in a chronological order I have studied closely the most significant texts to the topic with which this study is dealing.¨ I think it would sound more correct if you said: I have studied closely, in chronological order, the most significant texts dealing with the topic of this study.

Sorry , I just wanted to know if the sentences are correct and understandable. Thank you

Well, it's quite not clear that what you're asking- maybe, what's the meaning of 'Chronological Order' ?
