Promanteia was the privilege, bestowed upon cities or individuals by the Oracle of Delphi, to ask the Pythia in priority.
History
In the course of the classical period the priests of Delphi established a series of honours bestowed upon those who offered benefactions to the sanctuary, whether they were cities or individuals. The institution of promanteia was one of the privileges offered initially to cities which had offered aided the sanctuary financially. Promanteia was in fact the right to acquire an oracle before the others (yet still after the priests and the citizens of Delphi). Given the fact that oracle-giving was taking place on specific -and limited- periods of time, this right could actually be very important. From the beginning of the 4th century B.C. this right continued to be accorded to individuals and to be combined with other privileges, such as prothysia and proxenia.
