This is the reason of that constant site

Of Comets tayls and beards: And that their show’s

Not pure Pyramidall, nor their ends seem streight

But bow’d like brooms, is from the winds that blow,

I mean Ethereall winds, such as below

Men finden under th’ Equinoctiall line.

Their widend beards this aire so broad doth strow

Incurvate, and or more or lesse decline:

If not, let sharper wits more subtly here divine.
