The Lives and Opinions of Eminent Philosophers by Diogenes Laertius (third century AD) are transmitted (entirely, partially, or in the form of excerpts) by a hundred or so manuscripts. The oldest witnesses of this tradition are three continuous manuscripts (B, P and F), datable between the end of the eleventh century and the thirteenth century, and three collections of excerpts, two (Φ/Φh) copied in a Vatican MS of the twelfth century (and in its descendants) and the third in a MS in Vienna (Vi) written and dated 28 July 925.
