Figures of Earth by James Branch Cabell

In the morning Dom Manuel arose early, and left Niafer still sleeping with the baby. Manuel came down through the lower hall, where the table was as the revelers had left it. In the middle of the disordered room stood a huge copper vessel half full of liquor, and beside it was a drinking-horn of gold. Manuel paused here, and drank of the sweet heather-wine as though he had need to hearten himself.

He went out into the bright windy morning, and as he crossed the fields he came up behind a red cow who was sitting upon her haunches, intently reading a largish book bound in green leather, but at sight of Manuel she hastily put aside the volume, and began eating grass. Manuel went on, without comment, toward the river bank, to meet the image which he had made of clay, and to which through unholy arts he had given life.
