Liber de Mirabilibus Romæ ex Registro Nicolai Cardinalis de Amagonia in Bibliothecâ St. Isidori Armario IV., No. 69. This treatise, with some short but pertinent notes, has been published by Montfaucon (Diarium Italicum, p. 283-301), who thus delivers his own critical opinion:
Scriptor xiiimi. circiter sæculi, ut ibidem notatur; antiquariæ rei imperitus et, ut ab illo ævo, nugis et anilibus fabellis refertus: sed, quia monumenta, quæ iis temporibus Romæ supererant pro modulo recenset, non parum inde lucis mutuabitur qu Romanis antiquitatibus indagandis operam navabit (p. 283).
