The Moon passes the Pleiades once each month re-enacting what is depicted on the Nebra Sky Disc 
discovered in 1999. http://www.lda-lsa.de/en/nebra_sky_disc/
This disk is considered one of the most important archaeological finds depicting the path of the Sun and the Moon passing the Pleiades.
This artifact dating to at least 1600 BCE was found near Nebra, Saxony-Anhalt in Germany.
The Nebra Sky Disk is 30 cm in diameter and is a bronze blue green with gold symbols. The symbols include the Pleiades star cluster between the Sun and Lunar Crescent suggesting this disk was a time gauge oriented to the rising and setting of the Pleiades alerting them to when the weather would change.
There are aspects of the disk that are also oriented to the seasonal cycles of the Sun. The disk is tracking Solstices at 82 degrees North Latitude exactly where the disk was found. This is a great 10 minute YouTube about the disk for those who want to know more!
