It was probably moved during the early Christian or medieval period, and was eventually used as building material in the construction of Fort Julien near the town of Rashid (Rosetta) in the Nile Delta.

Rosetta Stone (software) vocabulary. On 9 June 2008, Rosetta Stone introduced an addition to its Version 3 product line: Audio Companion, supplemental audio recordings of words and phrases. The student is meant to repeat the spoken words and phrases for practice and memorization. Unlike recordings based on the Pimsleur method, the Audio Companion provides neither narration nor translations. Rosetta Stone distributes the audio supplements on audio CD and as MP3 files. Each Audio Companion supplements one level of the language course, and each disc supplements a specific unit. Complete Version 4 course packages include Audio Companion material for each level.
