From the Wikipedia pages on the Voynich Manuscript and on Cornelis Drebbel (1572 – 7 November 1633, Wikipedia page [1]) innovater and builder of the first navigable submarine in 1620.

Richard SantaColoma has speculated that the Voynich Manuscript may be connected to Drebbel, initially suggesting it was Drebbel's cipher notebook on microscopy and alchemy, and then later hypothesising it is a fictional "tie in" to Francis Bacon's utopian novel New Atlantis in which some Drebbel-related items (submarine, perpetual clock) are said to appear.

His website article is [2] and information about a presentation by him is here [3]. His website is [4].

The vellum of the VM has, however, been dated to an earlier period than Drebbel.
