<p>the second is correct. What are the correct idiomatic phrases of "Contrast" ? I'm kind of confused on its usage. In contrast with... in contrast to... contrast with... etc... and apparently contrast between also works? Is "contrasting" even an appropriate form of contrast? :(</p>

1. According to no [less of an authority than was] than Parkman,
2. According to no [less of an authority than] Parkman,
3. According to no [less an authority than] Parkman,</p>
<p>Okay. I know that More/Less..... than is the appropriate idiomatic expression. is less of...than or more of... also acceptable? The first sentence is wrong obviously, and the 3rd one is correct. Would the 2nd one be correct as well? </p>
