John Wordsworth, Dictionary of Christian Biography and Literature (1911)
“ In 340 Constantine invaded the dominions of Constans and penetrated into Lombardy, where he was killed in a small engagement. His dominions then went to Constans, who thus ruled the entire West. Of his character we know little or nothing. He appears to have been a staunch Catholic, but his attack upon the dominions of his brother Constans does not put his character in a favourable light. His short reign makes him very unimportant. ”
