Dowson's duties as professor suggested his
Grammar of the Urdu or Hindustani Language (1862), and he also translated one of the tracts of the
Ikhwānu-s-Safa, or Brotherhood of Purity. His major work was
The History of India, as Told by Its Own Historians. The Muhammadan Period, which he edited from the papers of
Henry Miers Elliot, in eight volumes (1867–77). He compiled the
Classical Dictionary of Hindu Mythology and Religion, History and Literature (1879), and contributed to the
Encyclopædia Britannica and the
Journal of the Royal Asiatic Society. His theory of the
Invention of the Indian Alphabet, claiming a Hindu origin, met with little support. ==Notes==
