During his tenure at Vyšehrad he may have taken a pilgrimage to Rome and sometime in the early eighteenth century he lived a prayerful and hermit-like existence at Waldstein Castle near Turnov.
His magnum opus is Cappella Regia Musicalis (Prague, 1693), containing 772 pieces, which was almost certainly the fruit of his 12-plus years as a provincial cantor.
Cappella Regia Musicalis is a massive collection of hymns, sacred and festive songs, and all manner of musical settings of almost all central parts of the Roman Catholic liturgy, all printed primarily in Czech.
Unlike most other Czech hymnals, many pieces in Holan's collection also included basso continuo and even obbligato instruments such as violins, viols, and trumpets.
Sections of Cappella Regia Musicalis were continually copied and reprinted throughout the ensuing centuries and, in some quarters, have been the basis for many Czech hymnals.
