While Constantijn Huygens is often credited as the sole author of Dagh-werck, there is some evidence to suggest Van Baerle played a role in its creation.

Handwriting in one of the preserved manuscripts of Dagh-werck it appears Van Baerle wrote or transcribed a substantial portion of the work.

[2] Huygens was not the only prominent scholar to recognize Van Baerle's intellectual prowess.

After Descartes received Constantijn Huygens' comments on a draft of his Dioptrique he wrote back "if Madame de Zulichem [sic] would like also to add her own corrections, I would consider that an inestimable favor on her part.

"[3] Van Baerle was born in Amsterdam as the daughter of the wealthy merchant Jan van Baerle (d.1605) and Jacomina Hoon (d.1617) whose early deaths left her a wealthy heiress at a young age.
