This lesson I have enjoyed learning about Chronological Topography. I found it interesting actually picking out the bits of a text which tell us about the period of time the writing was about. When you are reading a text you subconsciously take in this information in order to know what point in time the writer is talking about, but you do this without realising exactly what it is that is giving you this detail.
What tense the writer writes in gives us a good idea on whether this part of the text is retrospective (looking back) i.e. speaking from the future, looking to the future, or talking about the present time.
