Domnei by James Branch Cabell

Now Melicent abode in the house of Demetrios, whom she had not seen since the morning after he had wedded her. A month had passed. As yet she could not understand the language of her fellow prisoners, but Halaon, a eunuch who had once served a cardinal in Tuscany, informed her the proconsul was in the West Provinces, where an invading force had landed under Ranulph de Meschines.

A month had passed. She woke one night from dreams of Perion -- what else should women dream of? -- and found the same Ahasuerus that had brought her news of Perion's captivity, so long ago, attendant at her bedside.
