The date of composition has proven to be very difficult to determine.

If one accepts this theory, it suggests a date of composition as some time in early to mid-1592.

The true date of composition probably falls in the middle-1680s rather than 1689.

This places the date of composition as most likely somewhere between early 1592 and September 1593.

It is not always possible to give precise dates of composition for the early works.

The actual date of composition, however, has proved more difficult to determine.

There is a separate question concerning the date of composition however.

The actual date of composition is estimated between 1190 and 1204.

The date of composition is unknown, but he probably worked on it periodically between 1911 and 1928.

No actual date of composition is given in the manuscript.
