This page gives an overview of all articles in the 1911 Brittanica which are alphabetized under Ded to Dep.
Osiris and Isis are closely connected with Syria and the Lebanon in legend; the Ded or sacred pillar of Osiris is doubtless really a representation of a great cedar with its horizontally outspreading branches; 8 another of the sacred Egyptian trees is obviously a cypress; corn and wine are traditionally associated with Osiris, and it is probable that corn and wine were first domesticated in Syria, and came thence with the gods Osiris and Re (the sun god of Heliopolis) into the Delta.

112), makes two incidental references to Bacon's writings, but never mentions Bacon as he mentions Galileo, Kepler, Harvey, and others (De corpore, ep. ded.), among the lights of the century.
At other times the ceremonial was more mysterious and symbolical, as in the feast of the raising of the Ded-column when a column of the kind was drawn by cords into an upright position.
