 For the rest the cursive of the Codices remains fairly true to the square text.Documents of a private nature were certainly written in a much more running hand, as the sample from one of the oldest Arabic letters written with Hebrew letters (possibly the 10th century) clearly shows in the papyrus, in "Führer durch die Ausstellung", Table XIX., Vienna, 1894, "(compare Figure 3, column 4)".However, since the preservation of such letters were not held to be of importance, material of this nature from the earlier times is very scarce, and as a consequence the development of the script is very hard to follow.
