In Chapter 1 of “Origin” by Dan Brown there is a following sentence:
Langdon pondered the creature a bit longer and then continued along a suspended walkway, descending a sprawling terrace of stairs whose uneven treads were intended to jar the arriving visitor from his usual rhythm and gait.
And my questions:
- What does “jar … from his usual rhythm and gait” mean? “have his usual rhythm and gait lost”?
- Does “the arriving visitor” refer to professor Langdon in this case?
As a non-native speaker of English, I’d be most grateful, if you could answer my questions. Many thanks.
