What do you mean with "1577 period"?Is this true for ship of the 1577 period? thanks again,
What are you base this argument on? As far as I know, this drawing was prepared in collaboration with Anderson. And Anderson is quoted by many in their books (include James Leest who almost rewrite Anderson's book of rigging with more drawings) because he (Anderson) did very accurate research on the rigging of ships in the golden age. So this drawing is made up from drawings/paintings and models from that time. And therefore very usefull to use on a ship like the Revenge.The drawing may or many not be a reliable source
