Adriano La Regina (formerly Rome's archaeological superintendent 1976–2004, professor of Etruscology at Sapienza University of Rome),[7] Professor Fausto Zevi (professor of Roman Archaeology at Rome's La Sapienza University)[8] and Professor Henner von Hesberg (head of the German Archaeological Institute, Rome)[9] denied the identification of the grotto with Lupercal on topographic and stylistic grounds. They concluded that the grotto is actually a nymphaeum or underground triclinium from Neronian times. The current scholarly consensus is that the grotto is not the Lupercal and that the cave was located lower southwest, closer to piazza Sant'Anastasia al Palatino.[10][11]
