Concept of honor in Thucydides

Given our discussion in class, I thought I might add the following summary. 

1. The obligation to the dead, to the "fathers", to ancestors. Burial rites. 

2. Allowing enemy military leaders opportunities to speak before battles or before sieges. 

3. The importance of the city and its good preceding that of the individual. 

As for #3, it seems worthwhile to mention that those civic goods, if you will, do not extend beyond the city, nor to citizens of other cities. 

And some other possible additions:

4? The "law of Hellas," which Robert mentioned in class, and I think I explicated as a law of identity and obligation to other Greeks, specifically before non-Greeks, or Medes, or Persians, or "barbarians."

5?
