Anthon stands on the left bank of the river Rhône opposite its confluence with the Ain, about 30 kilometres upstream from the centre of Lyon.

His distant descendant, Louis d'Anthon disappeared in 1326; the manor was awarded to his younger sister, who ceded it to her aunt, spouse of Hugues de Genève.

The d'Anthon family survived some time through a cadet branch, the Varaxs which died out in the fifteenth century.

He set out on the way from Anton to Colombier which winds through the woods but there were 1,600 soldiers from the Dauphiné (that is to say his enemies) lying in ambush in the thickets near the village of Janneyrias.

The Orangist (supporting the House of Orange), strung out along the narrow path, was sorely surprised throughout.
