Byrd: Senex puerum portabat

Senex puerum portabat:
puer autem senem regebat:
quem virgo peperit,
et post partum virgo permansit:
ipsum quem genuit, adoravit. 

translation by William Mahrt
The old man carried the child,
but the child ruled the old man;
him whom the Virgin brought forth,
and after childbirth remained a virgin
him whom she bore, she adored.
