Parallelepiped
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).
