Hyacinthia

The first day was given over to mourning for the death of the hero: sacrifices were offered to the dead, banquets were stark and without pomp or decoration, and the sacrificial breads were very plain.

Numerous sacrifices were offered, exclusively goats, with the occasion of the κοπίς, kopis, banquets where the citizens invited their friends and relatives.

The kopis took place under special tents known as σκηναί (skēnaí), a characteristic trait of ancient country festivals.

Xenophon, in the Hellenics IV, 5, 11, reports that the Spartans interrupted their campaigns in order to be able to return to Laconia so as to participate.

According to Thucydides, upon the peace of Nicias, Athens, in order to prove its good will towards Sparta, promised to assist at the celebrations.
