There is unfortunately no portrait known of Hariot, and we can form no
idea of his personal appearance; but, fortunately, the drafts of the
three Latin letters to his eminent friend at Court, alluded to above,

Treatise 2, Lecture 26, page 307:

Northumberland, the favourer of all good learning, and Mecænas
of learned men, maintained while he was in the Tower for their
worth and various literature

A great deal of misconception has hitherto prevailed respecting Hariot's
great printed work on Algebra. His reputation as a mathematician has
been permitted to hinge chiefly upon it, very much to his disadvantage.
A brief bibliographical statement of facts will probably present the
matter in a new light. But first let the book be described as it lies
before us and has been described by many others since the days of
Professor Wallis, nearly two hundred years ago. The Title is as follows
