Apollo and the Muses on Parnassus, 1784, Engraving, Sheet: 24 15/16 ? 35 1/16 in. (63. 4 ? 89 cm), Prints, Raphael Morghen (Italian, Naples 1758?1833 Florence), After Anton Raphael Mengs (German, ?sti nad Labem (Aussig) 1728?1779 Rome), One of the most significant commissions of the eighteenth century was the Parnassus painted by Mengs in 1761 for the Villa Albani, Rome, and hailed as a manifesto of the new style of Neoclassicism. The carefully differentiated Muses, accompanied by their mother, Mnemosyne, derive from ancient sculpture, while the setting, a small grove of laurels in which the Muses are grouped around their leader, harks back to Raphael's fresco in the Vatican
