Of Canicula. Chap. 39.
CAnicula is a full seruent starre, and ariseth in the .29. degrée of the signe that is called Taurus, as Albumasar sayth. In the arising thereof is a great disturbaunce of the ayre and weather. And of this starre the dayes, that bée called Dies caniculares, haue that name: in which dayes it is sull perillous to be let bloud, or to take laxatiue medi∣cines: that is for passing distemperaunce of the ayre in heate. And therefore in Aphorism. Hippocrates sayth, That be∣fore that starre Canis, and after that Starre, and vnder that starre Canis, lax∣atiue medicines noieth and groweth.*
There it is sayde in Commento, that before the rising of that Starre, and in the rising, and anono after the rising thereof, it is perillous to giue laxatiue drinkes. For then the ayre is hotte and drie. And that commeth of an hotte Page 138 signe, and of the hot starre, and of the Sunne, that is then with that star Ca∣nicula, in the signe that is called Leo: for with little medicine the bodie should be made too hot and to drie, and therevpon happely shuld come to a feauer. And also the medicine shuld wose and passe out, & work the lesse. For then holes and pores be open and wide, by reason of the heate of the aire. And there Galen saith, That strong heate without forth, draweth out the strength and vertue of the medicine. And therefore hot water is contrarye to laxation, if the heate of the aire be strong at that time. Also the inner vertue is then féeble, & is made more féeble by drin∣king, or by letting of bloud. And the Ca∣nicular daies begin in the fiftéenth Ba∣lends of August: and they end in ye Nonis of Septembris. And so they be euen fiftie, as it is sayd there.
