Cicero, De Div., II, 41, 85.
Marucchi wishes to make the east cave the older and the real cave of the sortes. However, he does not know the two best arguments for his case; Lampridius, Alex. Severus, XVIII, 4, 6 (Peter); Huic sors in templo Prænestinæ talis extitit, and Suetonius Tib., 63: non repperisset in arca nisi relata rursus ad templum. Topography is all with the cave on the west, Marucchi is wrong, although he makes a very good case (Bull. Com., 32 (1904), p. 239).
Cicero, de Div., II, 41, 85: is est hodie locus sæptus religiose propter Iovis pueri, qui lactens cum lunone Fortunæ in gremio sedens, ... eodemque tempore in eo loco, ubi Fortunæ nunc est ædes, etc.
