PLATANONIS
a name that occurs but once (Not. Cur.) to designate a
locality on the Aventine in
Region XIII. Platanon means a grove of
plane trees and with this genitive vicus is perhaps to be understood.
This cannot be the platanon mentioned by Martial (iii. 19. 2) which was
in the campus Martius near the Hecatostylon (cf. Pr. Reg. 203). There
was probably yet another on the Esquiline, from which the church of
S. Eusebio was called 'in platana' in the tenth and eleventh centuries
(HCh 251).
