Romantic Poetry was written around common themes; themes that are evident in each piece of work. Some of the themes found in romantic poetry are: using nature as an inspiration or a basis for direction, writing as the author experienced the event or location personally, and describing past events or civilizations to give a sense of aged poetry. The themes aren't always clearly evident, some have to be rigorously deciphered through others.
The most clearly evident theme would be using "spots in time". In the poem Ode On A Grecian Urn, the entire poem is about an urn which tells a story of a past civilization, and the story has a lesson that remembering a past experience can be sweeter than living it. The past civilization is referring to a spot in time in which times were better and the person who created the urn is creating a way to remember and tell other people about a good time in the past. He isn't talking about the past in general, but a singular event or moment. Within the lesson it teaches, the writer isn't saying that he believes your entire past is sweet to remember, but a single event is sweeter to remember than to live it.
The poem Lines Composed a Few Miles Above Tintern Abbey also clearly demonstrates this theme, and it is demonstrated in two different interpretations of the phrase "spots in Time". The first way in which this poem demonstrates this theme would be how the author is talking of a physical place at a certain time. How the presence at this place at the time he is talking about, would have been a great time for someone. The other interpretation would be how this time, or spot, in author's life is better to remember than the way he actually lived it.
Within Ozymandias the entire poem is encapsulated within the theme of using "spots in time" to give a sense of the ancient. A man speaks for a good deal of the poem in how he will live on forever with his possessions, and how time is not an enemy of
