She could only remarry with judicial consent, when the judge was bound to inventory the deceased's estate and hand it over to her and her new husband in trust for the children.
If she did not remarry, she lived on in her husband's house and took a child's share on the division of his estate, when the children had grown up. She still retained her dowry and any settlement deeded to her by her husband.
Husbands of adulterous wives are advised not to remarry during the lifetime of the guilty party.
The modern Greek custom is "(a) that most candidates for Holy Orders are dismissed from the episcopal seminaries shortly before being ordained deacons, in order that they may marry (their partners being in fact mostly daughters of clergymen), and after their marriage, return to the seminaries in order to take the higher orders; (b) that, as priests, they still continue the marriages thus contracted, but may not remarry on the death of their wife; and (c) that the Greek bishops, who may not continue their married life, are commonly not chosen out of the ranks of the married secular clergy, but from among the monks."
Whether it was right or wrong to remarry while one had a husband living they did not discuss, for that question had evidently been settled by people "wiser than you or me," as they said, and to doubt the correctness of that decision would be to risk exposing one's stupidity and incapacity to live in society.
