Graces awakening Cupid, 1778-1781.

Mechanical painting of a clasical allegory by Francis Eginton after a painting by Angelica Kauffman or Ryland's 1776 engraving of it. The mechanical painting proces is considered significant for its use of an albumen surface and may be regarded as aquatint at an intermediate stage ready for transfer printing proceses akin to those used in ceramic technology.
