Pleiades, a group of stars occurring in that belt of the heavens called the zodiac, being those placed on the shoulder of Taurus. For the last weeks in May the Pleiades rise and set with the sun, so are invisible to us; but 2,000 years ago it was during the time corresponding to our April that they were not seen. After May the Pleiades rise every day earlier and earlier than the sun, till in August they have gained about 90°. During November they can be seen the whole night through, but after that the time during which they are visible gets less and less till May comes round again.
