AQUA ALEXANDRI(A)NA

* an aqueduct which takes its name from its con- structor, Alexander Severus (Hist. Aug. Alex. Sev. 25; cf. THERMAE NERONIANAE; Not. app., Pol. Silv. 545, 546). It seems to be referred to as forma Iovi in a document of 993 A.D. (Reg. Subl. No. 105, p. 151).

The springs were used by Sixtus V for the Acqua Felice (1585-7), but the whole course of the aqueduct was only identified in the seventeenth century by Fabretti (de aquis, Rome, 1680), whose accurate description of its interesting remains is followed by LA 380-393 ; LR 56. Its course from the third mile of the via Labicana towards the city is quite uncertain, and the 'nymphaeum Alexandri,' the so-called 'trofei di Mario,' is the terminal fountain of the AQUA IULIA (q.v.); though the piscina of the Vigna Conti, generally attributed to the THERMAE HELENIANAE (q.v.), may have belonged to it (LF 32). Cf. Jord. i. 1. 477-479; HJ 247-248, 350.
