Dear Friends It took a lot of time to prepare it but another great ancient book has just been released:
PERSPECTIVA HORARIA by Emmanuel Maignan Text from the original title page: PERSPECTIVA HORARIA SIVE DE HOROGRAPHIA GNOMONICA TVM THEORETICA, TVM PRACTICA LIBRI QVATVOR. In quibus Gnomonices antiqui fines latius protenduntur: traditurque ratio, & delineatio Geometrica expeditissima non solum communium, quœ radio directo vel vmbra pariter directa; fed etiam aliorum nouœ inuentionis Solarium horariorum, quæ radio vel vmbra tum reflexis tum refractis horas, aliaque ad cœlestium motuum notitiam pertinentia indicant. Operetta assai diletteuole per il nuouo, & vniuersal modo d'operare, in qual si sia Horologio Riflesso. In his vero præcipuam admirationem habet Thaumantias Catoptrica atque Dioptrica, id est reflexus, ac refractus a speculo cylindrico solaris radius, omnes, qui in Sphæra cogitari possunt, circulos gnomonice reddens Iridis modo ac specie: Lux quoque secundum propriam naturam sumpta suas ibi habet partes, ubi e principijs eius physicis ratio redditur reflexionum, ac refractionum eiusdem. Confequitur vero methodus certissima telescopium efficiendi non modo sphœricum fed etiam hyperbolicum atque ellipticum. Autore R. P. F.
