Elamite language
Scholars have been comparing the Indus valley script with Linear Elamite, as the two languages were contemporary to each other. One of the best sources of knowledge regarding the Elamite language is a bilingual monument called the "Table of the Lion" currently in the Louvre museum. The monument is written in both Akkadian, which is a known language, and in Linear Elamite. On comparing this ancient language to the Indus script, a number of similar symbols have been found.
