Death and the Afterlife. Ukrainians observe ancient funeral traditions very faithfully. A collective repast follows funeral services and is repeated on the ninth and fortieth days and then again at six and twelve months. An annual remembrance day called Provody on the Sunday after Easter gathers families at ancestral graves to see off once again the souls of the departed. Provody is widely observed in contemporary Ukraine. Under the Soviets it symbolized an ancient tradition. Its Christian symbolism represents Christ's victory over death. Its pre-Christian roots are attuned to the rebirth of nature in the spring and to an ancient ancestors' cult.
