That place that does contain
My books, the best companions, is to me
A glorious court, where hourly I converse
With the old sages and philosophers;

With kings and emperors, and weigh their counsels;
Calling their victories, if unjustly got,
Unto a strict account, and, in my fancy,
Deface their ill-placed statues. [ Beaumont and Fletcher ]
