Dioscorides Materia Medica

Although many reports have been made, not only in the past, but also recently about the production, effects, and testing of medicines, I nevertheless intended to instruct you, dear Areios, about them: the decisions to undertake such a thing is neither needless nor injudicious, for some of my predecessors have not completed their works, and others have written most things down from hearsay.

New Testament

Luke 1:1-4

1 Now many have undertaken to compile an account of the things that have been fulfilled among us, 2 like the accounts passed on to us by those who were eyewitnesses and servants of the word from the beginning. 3 So it seemed good to me as well, because I have followed all things carefully from the beginning, to write an orderly account for you, most excellent Theophilus, 4 so that you may know for certain the things you were taught.
