Zeus is depicted as a male aristo with long hair and a cloak with elaborate patterning.
The consensus or Majority opinion is that his eagle was a Golden Eagle seen as the King of the birds because it was one of the largest bird species known to the Greeks.
A note on technique. The reds and blacks are a clay slip of iron oxides. The higher the iron content the darker the slip. The yellow ochre lines are a technique called sgraffito of making lines by scratching thru the slips down to the base clay with some kind of stylus.
