The Old Testament Hebrew Massoretic, Greek Septuagint (LXX), Latin Vulgate, and Luther German texts, in four columns; the New Testament in Greek and Latin and German, the last column annotated with critical notes and variants. 1863. (link to Archive.org)
It's not the Complutensian Polyglot but it is an interesting source, especially if one knows a bit of older German or Latin better than one knows Greek or Hebrew. In any event, a helpful resource for comparing Luther's translation to the Vulgate, the LXX, and the original texts.
