Origin of the work:
1640 – 1656 Leszno
never appeared in print; the MS was destroyed in the Leszno fire of 1656
A tract that Comenius wished to fill out with scientific research on the new, syncretic method.
It was here that Comenius most thoroughly justified his syncretic method, linking comparison to the use of analogy (similarity, parallels). He provided his own critique in the Ventilabrum sapientiae (Breath of Wisdom; the Ventilabrum), greatly regretting the loss of this work on the syncretic method, for which he had found the model in Holy Scripture, and which in his opinion meant a great deal for the advance of science.
