Suso was very widely read in the later Middle Ages. There are 232 extant manuscripts of the Middle High German "Little Book of Eternal Wisdom". The Latin "Clock of Wisdom" was even more popular: over four hundred manuscripts in Latin, and over two hundred manuscripts in various medieval translations (it was translated into eight languages, including Dutch, French, Italian, Swedish, Czech, and English). Many early printings survive as well. The "Clock" was therefore second only to the "Imitation of Christ" in popularity among spiritual writings of the later Middle Ages. Among his many readers and admirers were Thomas à Kempis and John Fisher.
