Meddai Syr Marsiant Williams, yn y Nationalist am Fedi, 1908,—
"In fact neither Ceiriog nor Islwyn was a perfect master of style from a grammarian's point of view. . . . . But, but they were the greatest Welsh poets of their generations, and no one has risen to challenge their supremacy. Had Ben Bowen lived! But there, why should I prophesy? This is the hour for sorrow, for poor Ben Bowen died in the blossom of his youth full of promise, O what a fall was there my countrymen.'"
Ac meddai Mr. Tom Jones, un o ysgolfeistri y Rhondda, yn y Rhondda Leader,—
"His poetry is unique because of its ever newness and freshness, ever breathing and uttering the sublimest truths which are the heritage of his race and the earnest of the dawn he so fondly loved. Its whole being rose from that innate life of his, directed and environed by that majestic, divine intuition, so characteristic of all prophetic poets. Herein he bears a fellowship with Wordsworth, Keats and Browning. He was the creator of a new school of poetry in Wales: he ushered in the new light of liberty and freedom: he was ever reaching for the dawn. He was a child of the future and the heir of the past. Sings he not thus,—
"'Rwyf yn blentyn y dyfodol
Sy'n etifedd y gorffennol."
