The first and second principal components (joy-sadness and anger) explain only 41% of the variance. I wish the authors showed further principal components. Even principal components 1-4 would explain no more than 70% of the variance, which seems to contradict the popular theory that all human emotions are composed of 5 basic emotions: joy, sadness, anger, fear, and disgust, i.e. 4 dimensions.
Interesting. Apion's description of the pessoi game mentioned in the Odyssey: flicking pebbles toward the Penelope-pebble convinces me more than translating pessoi as draughts. The problem with Apion's description is:
- There were 108 suitors (we know this from the Odyssey 16.245-254 [1]).
- All that Homer told us is: They were gladdening their hearts at pessoi in front of the doors, sitting on the hides of oxen which they themselves had slain (the Odyssey 1.106-108 [2]).
- You can't have 108 sitting men play the same game of marbles.
IMHO, pessoi was a 1:1 game and it was not a board game.
