Historical astronomical lunar tables I hope this is the right place to ask this question, and I apologise if not.

I've come across a date written in an old book, but it is written using what seems to be a lunar/zodiac system.
Below is a picture of the date (ignore the text above it):



I'm trying to work out what this date would have been in our modern calendar, but I can't seem to find any tables or almanacs that go back that far.

Are there any publicly available tables that do go back to 1587? If not, how exactly could I go about calculating the answer for myself? I am a mathematician, so a bit of wacky maths should be within my capabilities.
This is the answer I'm probably expecting from this site: some kind of program/algorithm/formula to be able to work out on what date the moon would have been in Taurus in

If not, any ideas as to where best for me to ask/look next?
You can calculate this using the program "KAIROS", See here: http://www.raymondm.co.uk/
It will let you play through the variables: Is this a Julian or a Gregorian date? Is it using true or mean positions? And so forth.
