Gibbon tells us of the man:
“The person, as well as the mind, of Constantine, had been enriched by nature with her choices endowments. His stature was lofty, his countenance majestic, his deportment graceful; his strength and activity were displayed in every manly exercise, and from his earliest youth, to a very advanced season of life, he preserved the vigor of his constitution by a strict adherence to the domestic virtues of chastity and temperance. He delighted in the social intercourse of familiar conversation; and though he might sometimes indulge his disposition to raillery with less reserve than was required by the severe dignity of his station, the courtesy and liberality of his manners gained the hearts of all who approached him. The sincerity of his friendship has been suspected; yet he showed, on some occasions, that he was not incapable of a warm and lasting attachment.
