Swedish men who travelled to Denmark, England, or Saxony and the Byzantine Empire played an important part in the introduction of Christianity in Sweden, and two runestones tell of men baptized in Denmark, such as the runestone in Amnö, which says "He died in christening robes in Denmark." A similar message is given on another runestone in Vallentuna near Stockholm that tells that two sons waited until they were on their death beds before they converted: "They died in (their) christening robes." Christening robes or baptismal clothes, "hvitavaðir", were given to pagan Scandinavians when they were baptized, and in Uppland there are at least seven stones that tell of convertees having died in such robes.
