describe the stranger that arrives at the cottagers' hut that the creature refers to as "the arabian"?

From the text:

"It was a lady on horseback, accompanied by a countryman as a guide. The lady was dressed in a dark suit, and covered with a thick black veil. Agatha asked a question; to which the stranger only replied by pronouncing, in a sweet accent, the name of Felix. Her voice was musical, but unlike that of either of my friends. On hearing this word, Felix came up hastily to the lady; who, when she saw him, threw up her veil, and I beheld a countenance of angelic beauty and expression. Her hair of a shining raven black, and curiously braided; her eyes were dark, but gentle, although animated; her features of a regular proportion, and her complexion wondrously fair, each cheek tinged with a lovely pink."

At the outset of spring, a stranger ­ an exquisitely beautiful young woman of exotic appearance ­ appears at the family's cottage. Felix is ecstatic to see her, kisses her hands, and refers to her as his "sweet Arabian"; later, the creature learns that her true name is Safie.

The creature notes that her language is different from that of the cottagers, and that the four humans have great difficulty in understanding one another. They communicate largely through gesticulation, which the creature is initially unable to interpret; he soon realizes, however, that the cottagers are attempting to teach Safie their language. He secretly takes part in her lessons and, in this way, finally begins to master the art of speech.
