The
autograph manuscript of the
Deeds, known as the
Codex Sancti Gisleni, survives in
The Hague (MS Den Haag KB 75 F15). It is incomplete. The last part, from the middle of chapter 49 onwards, had been separated from it and lost sometime in the 14th century. There are five manuscript copies of the
Deeds representing three
recensions. The oldest surviving copy, dating from the 14th century, is in Paris (
BnF, Lat. 5553a). It is a complete copy made from the autograph before it lost its final eleven and a half chapters. A separate tradition derives from the now lost 12th-century
Codex Sanctae Mariae Atrebatensis, which contained a complete copy of the autograph. The earliest copy of the
Codex was made in the
Abbey of Saint-Vaast in 1482 and is now in the municipal library of
Arras (Médiathèque 666). It was itself copied in 1591 by
François de Bar, whose copy is now in Brussels (
KBR 7747). Both of these copies are riddled with errors. There is also a late 16th-century copy of the
Codex in Paris (BnF, Lat. 12827). A further 16th-century copy in Brussels (KBR 7675–82) represents a third manuscript tradition, but is missing chapters 52 and 60 of the third book, Gerard's sermon on
Peace of God movement and his letter to the
Emperor Henry III, respectively. The first printed edition of the
Deeds was made by in 1615. Because he made use of the now lost
Codex, his edition has been used as a basis for two subsequent editions. The first of these, by in 1834, omits several chapters in the second and third books. The second and most recent, by for the
Monumenta Germaniae Historica in 1846, is the basis for the modern English translation published in 2018. ==Dating and authorship==
