The Aqua Crabra is described by Cicero in his treatise De Lege Agraria ("On the Agrarian Law") where we learn it supplied his villa near Tusculum.[1][2]
The aqueduct is also attested in the text of Frontinus.[3][4]
The Crabra is sometimes referred to as Aqua Mariana or Aqua Maranna del Maria.[5]
The evidence offered by CILVI, 1261 was interpreted by Mommsen to be connected with the Aqua Crabra, even though there is no specific mention of it in the fragmentary text.[6]
Archaeological discoveries announced in December 2014 in conjunction with Rome's Metro C excavations have been preliminarily linked with the Aqua Crabra. This discovery consists of a large hydraulic reservoir, perhaps the largest known from the ancient city, along with a water wheel and agricultural implements.[7][8]
