A Lark found no place to bury her father and so used her head. This is why the Lark now has a crest.
Youth’s first duty is reverence to parents.
Townsend version
The lark (according to an ancient legend) was created before the earth itself, and when her father died, as there was no earth, she could find no place of burial for him. She let him lie uninterred for five days, and on the sixth day, not knowing what else to do, she buried him in her own head. Hence she obtained her crest, which is popularly said to be her father’s grave-hillock.
Moral
Youth’s first duty is reverence to parents.
Galerita et Pater Eius
Aesopus ait galeritam, avium primam omnium, ante terram generatam fuisse, ac deinde patrem eius morbo extinctum, cum terra non esset, quinque dies insepultum iacuisse; illam autem, quidnam ageret incertam ob rei difficultatem, patrem denique in capite sepeliisse.
