Gap-toothed I was, and that became me well;
I had the print of holy Venus’ seal.
So help me God, I was a healthy one,
And fair and rich and young and full of fun;
And truly, as my husbands all told me,
I had the silkiest quoniam that could be.
For truly, I am all Venusian
In feeling, and my brain is Martian.
Venus gave me my lust, my lickerishness,
And Mars gave me my sturdy hardiness.
Taurus was my ascendant, with Mars therein.
Alas, alas, that ever love was sin!
I followed always my own inclination
By virtue of my natal constellation;
Which wrought me so I never could withdraw
My Venus-chamber from a good fellow.
Yet have I Mars’s mark upon my face,
And also in another private place.
I confess, I don’t know if a gap between teeth is “Venus’ seal.” And what is “Mars’ mark” on her face? Probably a scar. But in the below quote there is no doubting that the author is talking about planetary detriment and exaltation:
The children of Mercury and of Venus
Are in their lives antagonistic thus;
For Mercury loves wisdom and science,
And Venus loves but pleasure and expense.
Because they different dispositions own,
Each falls when other’s in ascendant shown.
And God knows Mercury is desolate
In Pisces, wherein Venus rules in state;
And Venus falls when Mercury is raised;
Therefore no woman by a clerk is praised.
A clerk, when he is old and can naught do
Of Venus’ labors worth his worn-out shoe,
Then sits he down and writes, in his dotage,
That women cannot keep vow of marriage!
So, was Chaucer interested in astrology? Well, it sure looks like it: http://colfa.utsa.edu/chaucer/ec22.html
