Petrus de Thimo, Latinized name of Peter van der Heyden[1] (1393 - 26 February 1474), was a Brabantine chronicler and a lawyer employed by the city of Brussels, of which he became Pensionary in 1423.
He died a few months later and left two children: Petrus, who became dean of Anderlecht, and Catharina, who married Hendrik van der Male and had a son Jan who became a chronicler himself (Johannes de Thimo).
Very valuable are the texts of privileges, statutes and charters that can be found included in the chronicle (about the collegiate Sainte-Gudule, the city of Brussels and the Duchy of Brabant).
In addition, De Thimo commissioned a more famous chronicle, the continuation of Jan van Boendale's Brabantsche Yeesten (books 6-7).
[3] The author of this continuation, identified as Wein van Cotthem, drew from De Thimo's Brabantiae historia diplomatica, but also from his personal experiences.
