In this scene a handsome youth adopts a confident and slightly nonschalant pose completely naked except for a kynodesme.  In his right hand is a staff or perhaps a javelin showing that the context of the scene is an athletics event.

The kynodesme is at the centre of the picture.  The viewer's eye is immediately drawn there - the principal object of the scene is the kynodesme.

The kynodesme is neatly tied, binding the youth's foreskin and restraining his penis.  His scrotum is fully is now fully exposed and displayed.  He is now dressed for the part of an athlete in ancient Greece.

Whilst his pose points to the picture's left he is looking to the picture's right.  Is there something to the right of the scene that has attracted his attention?  There is a slight smile on his face and he seems pleased with himself  . Perhaps he is sharing a joke with a fellow athlete - the kynodesme must have had its humorous aspects.  Maybe another athlete fumbles to tie a kynodesme as neatly and fumbles himself to an erection - always a source of mirth amongst the Greeks.  

Or perhaps he is exchanging glances with a female admirer who's quite taken to his dapper dress sense.

This scene, on a vase, shows four characters.  To the right is a naked youth about to throw a discus. This youth is not wearing a kynodesme and his penis hangs loose.   A clothed official appears to point to his genitals so as to reprimand the athlete for the impropriety of starting without first fixing a kynodesme.

To the left another youth is about to fix a kynodesme to himself.  He is accompanied by a lad whose role is not clear.

Here the youth on the far left is about to fix his kynodesme. In his right hand he holds the kynodesme cord and with his left hand he firmly tugs his foreskin. His gaze shows how pre occupied he is with the task. The position of his legs may show the best pose to adopt when fixing the kynodesme.

Next to this youth is a lad wearing a cape that obscures his gentitals. The lad's gaze is firmly on the youth's genitals. Maybe the youth is tutoring the lad on how to fix a kynodesme.

The lad's right hand reaches out to the youth. Perhaps he is offering to participate in fixing the youth's kynodesme by pulling the youth's foreskin to that he has both hands free to firmly tie the kynodesme around his foreskin.

If the youth has a short foreskin or is partially erect (or both) he could well be in need of assistance. Especially if his event is about to start and he has yet to change into his sports gear.

In ancient Greece symposia were frequently male only drinking sessions.

In this scene the man in the centre is dancing or performing a jig. He is wearing a toga which, although having ample cloth, as evidenced by its numerous folds, hangs precariously from his shoulders down his back. His genitals are thus fully exposed and this is clearly on purpose. The man's penis is curled which indicates that he is wearing a kynodesme that is not depicted explicitly but inferred by the curled penis. The curling of the penis and the absence of a waist band mean that the kynodesme is of the type where the foreskin is tightly bound and secured to the base of the penis.

The purpose of the man's left hand is ambiguous. Most likely is that it is raised as part of his dance. But he could be adjusting his toga, either to keep it on or cast it off. The casual draping of the toga over his shoulder and down his back only emphasises his nakedness. His nudity is further emphasied by the wearing of a kynodesme and the consequential exposure and display of his scrotum.

On the right of the scene is a partially obscured man bearing a vase or a dish. He too is wearing a toga in the manner that reinforces his nakedness and he also wears a kynodesme. His is a side view and the upward curl is the penis and the exposure and display of the scrotum are clear.
