Revealing your own character in writing

Chaucer had himself depicted at the start of the verses

Now in that season it befell one day
In Southwark at the Tabard where I lay, 20 As I was all prepared for setting out To Canterbury with a heart devout, That there had come into that hostelry At night some twenty-nine, a company Of sundry folk whom chance had brought to fall 25 In fellowship, for pilgrims were they all And onward to Canterbury would ride.

This is the start of the poem as he began his journey and came into contact of these people. Chaucer presents himself as a courtly scholar is what i would say. His words and beautiful descriptions of the start of the season is breathtaking just to think about all the imagery that was presented. 

You can't really find Chaucer in the prologue rather piece of piece here and there. The other part i found was that he advised them to leave early at the start as well. 

His really polite in his story as he constantly asks for forgiveness if things turn sour or the language turn ugly. like lines 715-720

This is all i have found as to Chaucer appearing as a character in the story.
