Based on the intact beaker at the Corning Museum of Glass, Corning, NY. The lower frieze shows four standing horsemen:
HIHRAX (Hierax - 'The Falcon')
PYRAM (Pyramus)
CEGAS (Gegas - 'The Giant')
CRUSCUS (Cresces)
Each is being presented with a victor's palm and a laurel wreath by a winged Victory.
On the upper frieze, above each rider and standing between palm trees four horses are named: IXICIT, HIRPIN, CIAO and SACIPA. (IXICIT may be a corrupt rendition of 'Incitatus', meaning 'the rapid one', a name which is also used by a charioteer).
Although this beaker may be recording single horse and rider events, the fact that the names correspond with those of charioteers who drove both bigae (two-horse chariots) and quadrigae (four-horse chariots) suggests that the horses are probably representations of famous funales, the important leading or turning stallions in a pair or quartet. (Several later Roman mosaics show quadrigae, yet name only one of the four horses depicted, usually the horse on the driver's extreme left).
