Feeding the stars with questions

Kings made tombs more splendid than houses of the living, and counted old names in the rolls of their descent dearer than the names of sons. Childless lords sat in aged halls musing on heraldry; in secret chambers withered men compounded strong elixirs, or in high cold towers asked questions of the stars.
