Well, Christianity didn't exist at that point, and now that it does I'm not sure I'm qualified to recite it, but...I think I've heard one...

Absolve, we beseech Thee,
O Lord, the soul of Thy servant,
from every bond of sin,
that being raised in the glory of the resurrection,
he may be refreshed among the Saints and Elect.
Through Christ our Lord.

Amen.
