I disegni inediti di Xavier Pascal Coste di Antinoupolis e la porticus post scaenam del teatro.

The contribution examines five unpublished drawings made in Antinoupolis on 18 May 1821, by Xavier Pascal Coste, kept in the Fonds Pascal Coste at the Bibliothèque municipale de Marseille. Four of the drawings refer to a single monument: the Propylaeum which ended the main porticoed street of the city to the east, in the direction of the theatre. Thanks to this new documentation, together with the already known representations, a reconstruction of the monument is advanced, very relevant in terms of size and peculiarities. The fifth drawing presents two more enigmatic depictions, especially for one which depicts a portico on three sides, the location of which is not specified. It is proposed, very cautiously, that this portico could be the porticus post scaenam of the theatre. Beyond this hypothesis, the porticus post scaenam was undoubtedly present in Antinoupolis, with very relevant peculiarities and included in a very articulated urban program, to be traced back to the Hadrian foundation.
