Fortvnii Liceti ... De lvcidis in svblimi ingenvarvm exercitationvm liber : in quo disseritur de radiis solis directis nullam attritionem, nullamque caliditatem in aere producentibus, ad reflexorum refractorumque discrimen : de duplici galaxia, caelesti, & elementari : de cometis in caelo, & in ignis elemento genitis, tum per condensationem aetheris vtriusque sine grauitatis acquisitione; tum etiam per astrorum concursum, antiquioribus ignotum : de cometarum eclipsi : de cauda lucente solum in vmbra cometici capitis : & de nubium triplici differentia specifica, densiorumque leuitate summa cum puritate coniuncta. --
A Latin treatise on light in the upper air by the Paduan physician and natural philosopher Fortunio Liceti, printed at Padua in 1641 for scholars arguing over comets, the Milky Way and the heating power of solar rays. The scans hold dense roman and italic letterpress with running heads and catchwords, foxed blank leaves, and a red-printed armorial bookplate showing a dragon shield, a mailed fist with halberd and a motto ribbon—useful for crest devices, ribbon banners and aged paper grounds.
