Pneuma of taste
Gustatory extension — tongue / mouth
The pneumatic extension of taste, terminating in the tongue. Stoic physiology treats the tongue as a moisture-soaked terminus across which dissolved sapid substance is registered by the gustatory pneuma; sapidity is a relational property between the sapid object and the gustatory current. We place the rendered point at the chin-region landmark height as a stand-in for the tongue's interior position, since the silhouette renders the closed mouth as a single midline locus.

Diogenes Laertius, Lives VII.157 (primary_canonical)
Diogenes Laertius VII.157 names taste among the five sensory powers that belong to the Stoic eight-part soul. The citation supports the tongue as the gustatory termination of a faculty continuous with the hēgemonikon.
Aetius, Placita IV.21 (primary_canonical)
Placita IV.21 preserves Stoic physiological material concerning the peripheral powers of soul, including the sensory and generative extensions. It supports the gustatory extension shown here; the chin marker remains a rendering proxy for the interior tongue.
