His attributes are the trident and the dolphin (sometimes the tunny fish.) As represented in art Poseidon resembles Zeus, but possesses less of his majestic calm, his muscles are more emphasized, and his hair is thicker and somewhat dishevelled.
The fishermen and fisherwomen form a quite distinct class of the people; both sexes are noted for their bodily strength, and the men for their bold and skilful seamanship. Tunny and sardines are cured and exported in large quantities, oysters are also exported, and many other sea fish, such as hake, sea-bream, whiting, conger and various flat-fish are consumed in the country.

It had complete control over the Euxine grain-trade; the absence of tides and the depth of its harbour rendered its quays accessible to vessels of large burden; while the tunny and other fisheries were so lucrative that the curved inlet near which it stood became known as the Golden Horn.
The tunny fishery is considerable; it is centred principally in the south-west.
In 1902 there were 48 tunny fisheries, employjng 3006 men, and 5116 tons of fish worth 80,000 were caught.
Neither the tunny nor the coral fishery is carried on by the Sardinians themselves, who are not sailors by nature; the former is in the hands of Genoese and the latter of Neapolitans.
