parallel text is a text placed alongside its translation or translations.
Parallel text alignment is the identification of the corresponding sentences in both halves of the parallel text. The

Origen's
Hexapla (Gr. for "sixfold") placed six versions of the Old Testament side by side. Note also the most famous example, the
Rosetta Stone.
