Henry VIII spent almost an entire year's tax revenue celebrating Christmas in the first year of his reign, National Archive files reveal.
Expenses for 1509 show the 19-year-old king spent the equivalent of £13.5m on a series of lavish events. Total revenue for the year was £16.5m.
The money went on food, entertainment and gifts - including generous individual presents for staff.
Beneficiaries included choir boys, musicians, actors and servants.
The king paid his blind court poet, Master Bernard André, £5 - the equivalent of £2,400 in today's money, and another £1, now £483, to a woman who brought a perfumed ball to the palace residences to keep the air fresh.
One goldsmith was also offered £83 for gifts by the monarch, worth £41,000 in the present day economy.
