A sign of 'Mors de la pomme'

The government Adam's apple

A book of hours from 1503 by Jehan Pychore and Remy de Laistre. The text seemingly refers to Mors de la Pomme, but the meaning is different.
"Puis adam la genealogie / En signe du mors de la pomme". There is no connection between images and text. There's a larger version here: Adam's apple.
