My attention was drawn recently to this about Philip Henry. As one who is very much Calvus et Calvinus (bald and a Calvinist) I found it of interest.
With regard to Mr. Henry's bodily presence, he was of a middle stature, his complexion not approaching to any extreme, of a very pleasant aspect, and an unusual mixture of gravity and sweetness in the air of his countenance, which was the true index of the mind. In the latter part of his life he had but very little hair, and had, like Elisha, a bald head; notwithstanding he could not be persuaded to wear a wig, against which he had an insuperable objection. This lack was however supplied by his usually wearing a neat close cap or turban on the upper part of his head, made of black silk. When some of his friends solicited him to have his picture drawn, he put them off with this remark, that the best picture of a minister is in the hearts of his people.
