During the Ptolemaic era the number of signs was increased dramatically, from around 800 to several thousand, many of which were ligatures of existing signs. The rise in the complexity co-incided with the rise of so-called cryptographic texts in temple inscriptions that aimed to deliberately obscure and challenge the reader. The reasons for this are unknown, and various reasons from xenophobia, cultural pride and nationalism (see also: [[Great Egyptian Revolt]]) to marginalisation and isolation of traditional religion and the rise of Hellenic and syncretic cults have all been suggested.

The Roman era sees the decline of the hieroglyphic system of writing. The last surviving knowledgeable and literate hieroglyphic inscription in ancient times dates from August 24th, 396 AD and was inscribed in the temple complex of Philae, five years after Theodosius I forced the closure of all non-Christian places of worship in Roman territory. The inscription, the Graffito of Esmet-Akhom is catalogued as Philae 436 ([http://www.flickr.com/photos/mkubecka/2093092240/ picture]).
