 "Graves was a man of sound judgment, well trained intellect, and fertile imagination; his eloquence was copious; his manner was earnest, affectionate, and awakening; he was as noted for his simplicity as for his learning, for his benevolence as for his pastoral piety"

His portrait still hangs in Trinity College, Dublin, and in 1866 a memorial window of stained glass was placed in memory of him in the Chapel of Trinity College – the subjects selected were illustrations of the Pentateuch, in allusion to his work.One of his sons, Richard Hastings Graves (1791–1877), collected all his writings together and published them in four volumes in 1840.He had left a generous will, and was interred with many other members of his immediate family at a plot in Donnybrook Cemetery, where there is a plaque to his memory.
