These were Winter Solstice celebrations in which worshippers led the goddess in the form of a golden cow, covered by a black veil, seven times round the shrine of the dead Osiris in the temple of Helios in a perambulation called 'the seeking for Osiris'. This represents the wanderings of Isis who journeyed over the world mourning for his death and searching for the scattered parts of his body.
The birth of the divine child, whether he bears the name of Horus, Osiris, Helios, Dionysus or Aeon, was celebrated in the Koreion in Alexandria, in the temple dedicated to Kore, on the day of the winter solstice. Neumann, Erich, The Great Mother, Princeton Univ Press, 1972, p. 312
