The tiny inscription on the east facing side of the Pyramid of Cestius below the larger dedicatory one, records the circumstances of the tomb's construction: "This work was completed in accordance with the will in 330 days under order of Lucius Pontus Mela, son of Publius of the Claudia family, heir; and Pothus, freedman."
In his will, Cestius expressly asked his heirs to build his Egyptian-style pyramid tomb in 330 days. If the deadline was not met, the heirs would not benefit from the rich bequeathed inheritance.
Lucius and Pothus hurried in delivering the testament order, so much so that rumor has it the monument was completed a few days early.
A freedman is a former slave who has been released from slavery, usually by his owner.
Hollywood material, if you ask me.
