Five is attributed to Mercury, messenger, intermediary, healer; 5 "in holy things casts out demons and expels poisons' [Agrippa]. In relation to demons we may also note mercury is god of tricksters and deception, and five is the base of the triangular number fifteen, connected with the witches Sabbath [held on the fifteenth day of the moon], and with the 'Devil' card. It is one of the three 'spherical' numbers that make up the letters in the name of God [a spherical number is one which multiplied by itself retains itself in the product, that is 5 [as in 5x5=25] which is the letter Hei in Hebrew, 6 [6x6=36] which is the letter Vau and 10 [10x10=100] which is the letter Yod; thus three spherical numbers/letters = YHV or as it was transliterated in Greek IAO, the symbolism of which letters in either Hebrew or Greek allude to that being 'which was, is and will be' without end, as in a circle, a geometric figure composed of one line without beginning or end]. It is connected with marriage, but may also be connected with any ceremony in the liturgy of life, baptism, confirmation, marriage, death [five of swords, for example, may symbolise a funeral]. It is also connected with the 'golden mean' and the two golden triangles named after the twins castor and pollux [perhaps that both the pope and devil form a triangle with two 'twin' acolytes is an allusion to this?]. It also represents the mean of the numbers 1-9, the central point of a square of 9. The mean or golden mean is the exemplar or measure of virtue. As central point of the square of the nine digits it is the bridge between the others, and in trump V we see the pontiff [the bridge].
