I followed him down the path that wound this way and that, three times the length of the path we had climbed.
I analyzed this sentence grammatically:
- I is the subject
- followed is a verb
- him is the object
- down the path this way and that is an object modifier or complement (don't know which)
- three times is a quantifier and noun
But could not understand the grammatical status of "the the length of the path we had climbed."
