Guido Bonatti - Liber Astronomiae - On Horary

Concerning those matters which come easily

Those matters which come about easily and without suit, and also
without any difficulty, such that all of these problems are not worth
considering, are[ those that happen] when the lord of the Ascendant or
the lord of the querent, and the significator of the matter sought for are
being joined by trine, or sextile aspect, and with reception.
