The Pyrucheium (the mss. of Eusebius vary considerably in their spelling, but I have adopted that form which seems best supported) or Brucheium (as it is called by other ancient writers and as it is more generally known) was one of the three districts of Alexandria and was inhabited by the royal family and by the Greeks. It was the finest and most beautiful quarter of the city, and contained, besides the royal palaces, many magnificent public buildings. Comprising, as it did, the citadel as well, it was besieged a number of times, and it is uncertain which siege is meant in the present case. It seems to me most likely that we are to think of the time of the revolt of Æmilian (see above, chap. 11, note 4), in 260 a.d., when the Romans under Theodotus besieged and finally (just how soon we cannot tell, but the city seems to have been at peace again at least in 264) took the Brucheium. Valesius and others think of a later siege under Claudius, but that seems to me too late (see Tillemont, Hist. des Emp. III. p. 345 sq.).
