The above is Augustin Pajou's Mercure ou le Commerce from 1780. This shows the typical attributes of the god with which we are all familiar. What I am interested in is his winged hat. I'm trying to find when this particular design, a sort of steel helmet, is settled on. I can't find any examples of this exact design predating the Renaissance.
It has similarities to the travelling hat, sometimes winged, sometimes not, which Hermes wears in red-figure vases, such as that depicted in the Sarpedon vase by Euphronios depicted below:
The nearest Greek analogue I can find is on the Hermes Logios now in the Palazzo Altemps, though I can't be sure the head isn't a restoration.
Many Roman examples seem to dispense with any identifiable headpiece beyond the wings, as shown on the Gosbecks Mercury below.
Anyone got any observations, or other examples to present?
