The answers are plot, characterization, and mood.
All novels include those three elements. You cannot have a story without things happening (plot) and something/someone making them happen (characters). The synthesis of these elements, along with the style of writing, create the mood.
I'm not sure to which story you are referring, but here's what the symbols mean. A pendulum is the part of a clock (i.e. a grandfather clock) that counts the seconds as they pass. They would symbolize the unstoppable nature of time. An old man with a scythe might represent the grim reaper or another figure of death.
Both of these symbols have to do with growing older and moving on (dying).
Hope this helps! :)
