Whom did Henry V hire to write his Valentine's Day carrot Catherine of Valois?

Henry V did not hire anyone to write a Valentine's Day card for Catherine of Valois, as the concept of Valentine's Day cards and the specific details surrounding their relationship are more rooted in modern interpretations than historical fact. Henry V and Catherine of Valois were married in 1420 as part of a political alliance, and their romance is often romanticized in literature. The idea of a Valentine's card is more a contemporary notion rather than a historical event related to their courtship.
