Of the three mythological subjects two are in the Prado, namely the _Mars_ and the _Mercury and Argus_, while the third and most beautiful is the _Venus at the Mirror_ recently purchased for our national collection. These were all of them painted for the decoration of the royal palaces, and we may therefore suppose that the artist was not entirely at liberty either in the choice of his subject or in his method of treating it. Certainly he does not seem to have been fond of painting the nude, unless with men, and it is noticeable that he has posed his model in this case with more modesty and reserve than is to be observed in the pictures of Rubens and Titian. The Holy Church was sternly averse to this class of painting, in which, accordingly, none of the Spanish school indulged; but at the same time the royal galleries did not exclude the most exuberant fancies of Rubens, Titian, Tintoretto, and others, and Velasquez was in all probability commissioned by Philip to paint this Venus--and another which has perished--along with the Mars and Mercury without regard to the ecclesiastical authorities. But it is hardly surprising if Velasquez availed himself less fully of the privilege than a Flemish or Italian painter would no doubt have done, and has given us so chaste and beautiful a realisation of the goddess. Having regard to the scepticism with which this masterpiece was received in England at the time of its purchase for the nation it is worth quoting Senor Beruete's remarks upon it in that connection. "The authenticity of this work," he writes "has found numerous doubters in Spain, less on account of its subject--being the only nude female figure in the whole _oeuvre_ of Velasquez--than because so few people ever suspected its existence; but after it was exhibited at Manchester in 1857 and in London in 1890, it was recognised that its attribution to Velasquez was well founded. At the sight of the canvas all doubt vanishes. There, indeed, is the style, the inimitable technique of Velasquez." This, from the connoisseur who has devoted years of study to the work of the master, and who rejects such well established examples as the Dulwich _Philip IV._ and the _Admiral Pulido Pareja_, is surely more conclusive than the academic pedantry of ignorance masquerading as authority. * * * * * BARTOLOME ESTEBAN MURILLO (1617-1682) has always been accounted the most popular of the Spanish painters, and it is only in recent times that his popularity has faded into comparative insignificance on the fuller recognition and understanding of the genius of Velasquez.
