Source-derived summary

Giacomo Laderchi (c. 1678 – 25 April 1738) was an Italian Oratorian and ecclesiastical historian.

Biography and works

He was born at Faenza near Ravenna, and died in Rome.

He is chiefly known for his continuation of the "Annals" of Cardinal Caesar Baronius and Odorico Raynaldi, which he brought down from the year 1566 to 1571. His contribution, though of some usefulness, is not sufficiently critical and is encumbered with numerous unimportant documents. It appeared in Rome (1728–1737), and extends from volume XXXV to volume XXXVII in the latest edition of Baronius (Bar-le-Duc, 1864–83).

Laderchi was also the author of several other historical -hagiographical- works, two of which involved him in heated literary controversies. His voluminous "Life of St. Peter Damian" (Vita Sancti Petri Damiani, Rome, 1702) was mercilessly but excessively criticized in an anonymous work entitled: "Sejani et Rufini dialogus de Laderchiana historia S. Petri Damiani" (Paris, 1705).

When he published his edition of the "Acts of the martyrdom of St.

Editorial reviewA productive starting point for separating a subject’s documented career from later reputation and commemoration. The current lead gives the account dated anchors—1678, 1738, 1566, 1571—that can be checked directly. The linked authority record independently contributes the date 1678-01-01. For this dossier, Giacomo, Laderchi and Italian is the immediate research focus.
Editorial analysis

Why this record matters

The phrase “italian ecclesiastical historian” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Evidence profile

Biographical claims are most persuasive when dates, appointments and relationships can be traced to records created close to the events described. The source revision retrieved here is dated Aug 20, 2024. The linked authority identifier is Q5557894. VIAF identifies the subject as 14794371. The Library of Congress control number is no92015798. 3 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1678, 1738, 1566 and 1571.

Critical limits

Public reputation and documentary evidence do not always develop together; absence from a summary is not evidence of historical absence. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
