17 in History Edit
Like most numbers, the modern usage may trace it's history to a more ancient time, such is the case with the date of March 17th, also known as Saint Patrick's Day. March 17 is the day generally believed to be the death of St. Patrick, the British-born missionary who is credited with converting Ireland to Christianity.The 17th of the third month was also venerated at the day on which Egyptian god Osiris was murdered. Osiris was depicted with green skin, presumably due to his ancient connection with vegitation, and later his association with death and decay as a god of the Afterlife and mummification. This "Green Man" was connected with grains, especially those used in the making of beer. March 17th was also the start of the Bacchanalia, a drunken celebration of the deity Bacchus/Dionysus.

The Symbolism of 17 Edit
The 17th card in the Golden Dawn and Thoth tarot deck is The Star which resides on the 28th path. The number 17 indicates the powers of Key 7, The Chariot, working through Key 1, the Magician. This is the Higher Self in full control of its vehicle, and that vehicle is totally focused and dedicated to carrying out whatever its driver desires. Aquarius is the zodiac sign assigned to Key 17. Aquarius is symbolized by a water-bearer. Its two wavy lines are the alchemical symbol for dissolution, and further indicate dissolving one’s identification with the personality. This symbol also shows the lower “water” as a perfect and exact reflection of the higher “water.” 
The Number 17 is known as the Star of the Magi. It reduces to 8 (1+7), and was represented by an 8-rayed star associated with Venus and the Goddess.
Adding every number from 1 to 17 (1+2+3+4+5+6+7+8+9+10+11+12+13+14+15+16+17) equals 153. 17x9 also equals 153.
The number 17 is related to the number 153 and the "Measure Of the Fish" (265:153, approx. square root of 3) which is the ratio found between the height and width of the vesica pisces shape, also known as the "almond," the "fish bladder," or "Jesus fish," it is the Christian symbol of the fish. It also represents the source of creation and generation and is connected to the shape and idea of the female vulva. In the Bible, Jesus causes his desciples to catch a miraculous, and quite specific, haul of 153 fish. The shape is found in midaeval architecture, especially in the case of arches, and the floor plans of Cathedrals.
And the number 17 is associated with Noah's Ark (it rested on the Mountain of Ararat on the 17th of the month) and the Lord Jesus' resurrection (on the 17th as well). Amazingly, the Greek noun for "fish" in "153 big fish" occurs in the whole Bible in 17 verses.
