I solicited cities and men, whom I did not have the chance to visit in person, with frequent letters, asking them to share copies of hidden books or anything new they might possess; I did not hold back from prayers, gifts, exchanges, skill, or industry.

Porta uses the word "furniture" or "equipment" to describe his collection of scientific specimens and knowledge. might be more complete and enlarged.

I frequently remembered the sentiment of Cicero, who said: It is right that those who desire to hand down to memory the most useful, carefully weighed, and explored things for the human race should try everything. original: "Par est eos, qui generi humano res utilissimas & perpēsas, exploratasq; memoriæ tradere concupierint, cuncta tentare."

Nor was there ever lacking at my home an Academy This refers to the Academia Secretorum Naturae (Academy of the Secrets of Nature), a scientific society founded by Porta in Naples. Members were required to contribute a new discovery in natural science to join. of curious men who, by pooling their resources, devoted strenuous and eager effort to investigating and testing these matters, and who were the greatest help to me in organizing and enlarging this work. These things, therefore, with such great expenses, labor, and study...
