Location of inscriptions to the Celtic god Lugus in the singular (circles) or plural Lugoves (three-pointed stars). The green symbols (#13b81d) indicate spellings with LVG-, while the purple symbols (#ae16d5) indicate spellings with LVC-.
I also include, as possibly relevant, the location of an inscription to the "Lugunæ goddesses" (Lugunis deabus); this is shown with orange Venus symbols (#f48406).
