One of the largest collections of Imperial Aramaic texts is that of the Persepolis fortification tablets, which number about five hundred.[12] Many of the extant documents witnessing to this form of Aramaic come from Egypt, Elephantine in particular (see: Elephantine papyri). Of them, the best known is the Wisdom of Ahiqar, a book of instructive aphorisms quite similar in style to the biblical Book of Proverbs. In addition, current consensus regards the Aramaic portion of the Biblical book of Daniel (i.e., 2:4b-7:28) as an example of Imperial (Official) Aramaic.[13]
