Robert Herrick, Noble Numbers, "The New Year's Gift"
That little pretty bleeding part
Of foreskin send to me,
And I'll return a bleeding heart,
For New Year's gift to thee.
Rich is the gem that thou didst send;
Mine's faulty too, and small:
But yet this gift Thou wilt commend,
Because I send Thee all.
Notes: January 1 is the Feast of the Circumcision. The giving of New Year's gifts is an English custom predating Christianity but here adapted to the feast day for Herrick's purposes.
