Acis. [Greek .] (Greek & Roman Mythology.) A Sicilian shepherd, beloved by the nymph Galatea, and crushed under a huge rock by Polyphemus, the Cyclops, who was jealous of him. His blood gushing forth from under the rock was changed by the nymph into a river, the Acis, or Acinius, at the foot of Mount Ætna.

Thus equipped, he would manfully sally forth, with pipe in mouth, to besiege some fair damsel's obdurate heart,--not such a pipe, good reader, as that which Acis did sweetly tune in praise of his Galatea, but one of true Delft manufacture, and furnished with a charge of fragrant tobacco.
