 Mira, Omicron Ceti
Johann Hevelius observed it from 1659 to 1682, inserted it in his monumental work, Prodomus Astronomiae, and christened it "Mira", "the Wonderful", in his Historiola Mirae Stellae of 1662.
The period of Mira was first determined more acurately by Ismail Bouillaud of Paris to be 333 days, only about 1 day deviating from the modern value, no wonder because this period is subject to small irregular variations.
Because of the form of its light curve, Mira is roughly visible to the naked eye (i.e., brighter than about 6th mag) for 1.5 months before and 2.5 to 3 months after its maximum.
