The New York Times – Susann Cokal

?an elegantly ambitious archival thriller in which knowledge dwells in the secret underground places, labyrinthine libraries and overlooked artifacts that have been hallmarks of the genre from The Name of the Rose and Possession to Angels and Demons and The Historian. Angelology is richly allusive and vividly staged, with widescreen-ready visuals, a dewy but adaptable heroine and a dashingly cruel villain?a terrifically clever thriller?more [Umberto] Eco than [Dan] Brown, without the cloudy sentimentalism of New Age encomiums or Catholic treatises.
