O VS P

In the Poem's Ozymandias and Ponder both talk similarly about time being the protagonist.  In Ozymandias time is the destoryer of the the statue which symbolizes the past.  Over time the statue has become in worse and worse structure.  Similarly to Ozymandias Time in Ponder is the the factor of the destruction of aqueducts.  Both poems deal with the difficulty of history to remain and how over time someone's great work gets diminished by time.
