Lionel Henry Cust, Dictionary of National Biography… (1899)
“ As a portrait-painter Van Dyck may lack the precision of Holbein or tender intimacy of Cornelius Janssen, the directness and amazing technical skill of Velazquez or Frans Hals, the mysterious pathos of Rembrandt; but in his own manner he reigns supreme, and his genius needs no interpreter. It is curious that in England, where his fame ranks so high, Van Dyck's works can be studied only with difficulty, since they are so widely dispersed. ”
