Thus, says Crescini, we have twenty-four days from the first meeting to the acceptance of his court, and 135 days thenceforward to the possession, that is 159 days.[131]

Della Torre,[132] however, will have none of this reckoning, and seems to have proved that it is indeed inexact. To begin with, according to the Ptolemaic system, the sun moved round the earth and touched it as it were not only at its rising but also at its setting, so that the twenty-four days become twelve. This, however, is but a small matter, merely reducing the 159 days to 147. Crescini's chief error, according to Della Torre, is that he has added the first period of twelve (or twenty-four) days to the second of 135—making them immediately consecutive. Let us examine this matter somewhat closely.

In the Ameto Boccaccio tells us that the happy night which came at the end of the 135 days, the night in which he possessed Fiammetta, fell "temperante Apollo i veleni freddi di Scorpione." Now at what time precisely is the sun in the sign of the Scorpion? Andalò[133] tells us that at the end of the 20th October the sun is three and a half gradi in Scorpio, and that by the 15th November it is already entering Sagittarius. The sun then entered Scorpio on the 17th October and left it on the 14th November.[134] Somewhere between those two dates the loves of Giovanni and Fiammetta were consummated.

BOCCACCIO AND MAINARDI CAVALACANTI
By the Dutch engraver called "The Master of the Subjects in the Boccaccio."
"De Casibus Virorum." (Strasburg, 1476.)

Boccaccio tells us, if we interpret him aright, that twelve days after his innamoramento his lady showed him that she was pleased by his love. He then passes on to describe the long and faithful service he gave her:—

"Lungamente seguendo sua pietate

Ora in avversi ed ora in graziosi

Casi reggendo la mia voluntate,"[135]

and so on. Then he says:—
