The word appears as "parallelipipedon" in Sir Henry Billingsley's translation of Euclid's Elements, dated 1570. In the 1644 edition of his "Cursus mathematicus", Pierre Hérigone used the spelling "parallelepipedum". The "Oxford English Dictionary" cites the present-day "parallelepiped" as first appearing in Walter Charleton's "Chorea gigantum" (1663).
