The Old Kingdom viziers bore the composite title tAyty TAty (n) zAb. Further hieroglyphic signs, such as the phallus-sign and the addition mAa, were appended in some cases to this title.
The form of the vizier's title with the phallus-sign occurred frequently in a limited period of time. For the understanding of the usage of the phallus-sign in the vizier's title, contextualization is crucial.
Analysis and comparison of the title sequences of both, the viziers with the phallus-sign and those without, brought proof of clear distinction in the structure of titles between these two groups and indicated that the occurrence of the phallus-sign within the highest administrative title coincides with the social change regarding the state administration and royal family.
