Usage examples of "chrestomathies".

Yama and Telmon had most of the major verses of the Puranas by heart, and were guided by Zakiel to read extensively in chrestomathies and incunabulae, but while Telmon dutifully followed the program Zakiel set out, Yama preferred to idle time away dreaming over bestiaries, prosopographies and maps—most especially maps.
