Jane Welch Williams claimed that the figures in sub-panels d-s, occupying the margins of the window, represented participants in a procession offering wine to the Cathedral on the duplex feast of St Lubin (September 16th). Careful examination of the panels themselves does not support this very specific interpretation (which owed much to that author's preconceptions about how the window as a whole functions). Indeed, the range of gestures is far more suggestive of men advertising the quality of their wares or negotiating a price. Two of the men point to their own eyes, some present their goblets with only one hand, others gesture towards the vessel and so on - none of which is particularly suggestive of a sacred offering.
Personally I see no reason to suppose that these figures are in any way different from the wine cryers or tavern keepers depicted in panel 01 and subsidiary panels a-c.
