Of the time of James I (8)
I believe the answer is:
jacobean
'of the time of james i' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for jacobean that I've seen before include "Relating to James I's era" , "of 17th century design" , "Early Seventeenth-century" , "Early 17th-century" , "Of period when James I reigned" .)
