Cowan, Esq. _INTRODUCTORY_ So far as it concerns pictures painted upon panel or canvas in tempera or oils, the history of painting begins with Cimabue, who worked in Florence during the latter half of the thirteenth century. That the art was practised in much earlier times may readily be admitted, and the life-like portraits in the vestibule at the National Gallery taken from Greek tombs of the second or third century are sufficient proofs of it; but for the origin of painting as we are now generally accustomed to understand the term we need go no further back than to Cimabue and his contemporaries, from whose time the art has uninterruptedly developed throughout Europe until the present day.
