Note:

1 novel, 1 novella
• The 1833 preface covers the second work in its closing paragraph: "To the Tale of Alroy I have added the history of a Christian hero placed in a somewhat similar position ...".
• In the first edition (London: Saunders and Otley, 1833), all three volume title pages display the titles of both component works separated by a horizontal line. In the US edition (Philadelphia, 1833), the two volume title pages display the two component titles without a line. (Both 1833 editions may be viewed at HathiTrust, linked above.)
• The 1870 US publication Miriam Alroy: A Romance of Twelfth Century contains the same two works, although its title does not indicate the fact. Thus it is another edition of the same omnibus work.

Synopsis: The heroes of the two works are an eastern Jew, during the 12th century, and a Christian "placed in a somewhat similar position". The former is a Prince of the Captivity, or "an asserted descendant of David" who ruled the Jews for many purposes, although they acknowledged conquerors. --from the 1833 Preface
