In page Apollo:

"

The famous Apollo of Mantua and its variants are early forms of the Apollo Citharoedus statue type, in which the god holds the cithara, a sophisticated seven-stringed variant of the lyre, in his left arm.[1] While none of the Greek originals have survived, several Roman copies from approximately the late 1st or early 2nd century exist, of which an example is the Apollo Barberini.[citation needed]
