Furthering its commitment to the preservation of dialing knowledge and lore, The North American Sundial Society is pleased to sponsor the ShadowCatchers Collection – a series of digital facsimile reprints of rare works on dialing. Each volume in the series includes a reproduction of a centuries-old dialing text not readily available elsewhere. The digital versions of the books are presented in Portable Document Format (PDF) and they appear as the original. The books can be read (and printed) with either the Acrobat Reader or the Adobe eBook Reader (both of which programs can be provided free when ShadowCatchers volumes are delivered on CD-R disk). The volumes are also available via Internet download and, for a limited time, as hardbound printed books. |

NEW! Jacques Ozanam’s A Treatise of Gnomonicks -
A New Addition To The ShadowCatchers Collection ! Furthering its commitment to the preservation of dialing knowledge and lore, in 2001 The North American Sundial Society began its sponsorship of The ShadowCatchers Collection – a series of reprints of rare works on dialing. Each title in the collection reproduced a centuries-old dialing text not readily available elsewhere. And originally each title was available only for a limited time as a hardbound printed book. The entire collection is now available in economical softbound (perfect binding) printed volumes (and, of course, still available on CD). For previews of the volumes, general information and pricing on each title, and instructions for ordering the printed editions, go online to: http://stores.lulu.com/store.php?fAcctID=608855. AND Now … Volume VIII. Jacques Ozanam, A Treatise of Gnomonicks. Ozanam was a French mathematician famous for his popular math texts. These included a math dictionary, a course of mathematics, and a text on mathematical and physical recreations. The last of these went through at least 18 editions over 2 centuries. Ozanam's dialing was instructive and entertaining - it includes innovative ideas such as a geographic sundial showing the time anywhere in the world, various universal horizontal dials, and the first suggestion that one's own body could be the gnomon of an analemmatic dial. His texts also cover altitude, azimuth, lunar, reflection, refraction, portable and stereographic projection dials – all in addition to the standard instruction in drawing sundials on any plane. This treatise is from the 1712 English translation (by the noted Newtonian scholar J.T. Desaguliers) of Ozanam's 1693 Course of Mathematics. The addendum is a 1708 English translation of the set of Problems of Dialling included in the 1st edition (1694) of his Recreations Mathematical & Physical. |
