Abstract
The focus of this paper will be the critical material in the particular Life of Thucydides which is attributed to ‘Marcellinus’.1 After some preliminary remarks about the extant Lives, I shall identify the critical material to be discussed, and proceed to examine its composition and possible origin. I shall suggest that, like the biographical material, the critical passages are a compilation of material from different sources and show a variety of approaches. In discussing these approaches, I shall show that the critical passages contain different emphases, analytical skills and priorities, and vocabulary.
