Source-derived summary

Ridder Jacob Westerbaen (7 September 1599 – 31 March 1670), heer (squire) of Brantwyck-en-Ghybelant, was a Dutch poet.

Life

Westerbaen was born in The Hague, the son of a rope maker, and was initially schooled in the Staten-College, then as secretary and preacher of the Remonstrants of the Synod of Dort. There, he studied medicine, after which he established himself in 1623 as a physician in the Hague. Two years later, he married Anna Weytsen, the widow of Reinier van Groenevelt, despite opposition from her noble family.

He was a good friend of Constantijn Huygens. Later, he came into contact with Jacob Cats, Blasius (1639–1672) and Jan Vos (ca. 1610–1667), becoming good friends with all three. When Oldenbarnevelt was executed for political reasons, Westerbaen retained possession of the victim's walking stick, inspiring the Republic's great poet, Vondel, to his famous poem 't Stockske ("The Little Walking-Stick").

Westerbaen wanted to apply for work elsewhere: Ockenburgh near Loosduinen, where he lived from 1652 until his death. He described it in a poem imitating the style of Huygens.

For this dossier, Jacob, Westerbaen and Dutch is the immediate research focus.
Editorial analysis

Why this record matters

The phrase “dutch poet, physician and writer (1599-1670)” 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

The entry’s evidential value lies in the named roles, institutions and publications that can be tested against primary documentation. The source revision retrieved here is dated May 13, 2026. The linked authority identifier is Q2521825. VIAF identifies the subject as 58256540. The Library of Congress control number is n91056614. 3 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1599, 1670, 1623 and 1639.

Critical limits

Later biographies can compress uncertainty and repeat inherited reputations, so apparently settled claims may still require comparison. 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.
