A book or text written in seven different languages, or something that contains or uses seven languages simultaneously.
From Greek 'hepta' (seven) + 'glotta' (language), modeled on 'polyglot'. The term describes multilingual works, especially biblical texts translated into seven versions.
The most famous heptaglot is the Complutensian Polyglot Bible from 1520, which included seven parallel language columns—scholars could compare Hebrew, Greek, Aramaic, and Latin versions side by side to understand the original texts!
