Lucæ Gavrici ... Tractatvs astrologicvs in quo agitur de præteritis multorum hominum accidentibus per proprias eorum genituras ad unguem examinatis / Quorum exemplis consimilibus vnusquiso de medio genethliacus vaticinari poterit de futuris, quippe qui per uarios casus artem experientia fecit, exemplo monstrante uiam.
A 1552 Venetian astrology treatise by Luca Gaurico, printed in Venice for a scholarly readership of astrologers and genethliacs, who used it to test predictions against the recorded births of real people. The pictures are letterpress astrological diagrams: a square chart framed by diagonal lines, with a central panel of printed dates, planetary symbols and times in roman type. A designer might take the strict geometric framing, the tiny planetary glyphs, and the tidy hierarchy of centred printed text.
