Published Onsigtbare Geschapene Waarheden (Invisible Creation Truths), Letters 32, 33, 39 (L-108, L-111, L-135)

One of the surviving bundles of the letters that Gaesbeeck published.

This one, noted in Schierbeek's biography, had three, Letters 32, 33, and 39 (L-108, L-111, L-135). It also had Gaesbeeck's dedication, dated January 1, 1684, and the three letters unnumbered and separately paginated: vii + 8 + 32 + 19.

Because they were paginated separately, they could be sold in any combination and bound however the buyer wanted them to be.
