My Sundials program can do this. Just let me know the height of the person, your latitude, and your longitude, and I can generate a scale model of the dial. The dial my program generates uses a fixed point for the gnomon, not the moveable one Daniel referred to. If you have access to a PostScript printer, I can just forward you a file which you can download to the printer.

This kind is an analemmatic sundial which is described in several introductory books to sundials. It gives the time by the suns azimuth. Because the solar time is not only depending on the suns azimuth but also on the suns declination (varying seasonally), the gnomon (i.e. the person) has to take a special position within the sundial which is marked e.g. with the firsts of each month. ------------------ RFC822 Header Follows ------------------ Received: by po.gis.prc.com with SMTP;15 May 1996 04:01:02 U Received: by rs1.rrz.Uni-Koeln.DE id AA57860 (5.67b/IDA-1.5 for sundial-out); Wed, 15 May 1996 09:20:14 +0200 Received: from zeus.PH1.UNI-KOELN.DE by rs1.rrz.Uni-Koeln.DE with SMTP id AA57856 (5.67b/IDA-1.5 for <[email protected]>); Wed, 15 May 1996 09:20:13 +0200 Received: by zeus.ph1.Uni-Koeln.DE (1.38.193.4/16.2) id AA15667; Wed, 15 May 1996 09:15:55 +0200 Date: Wed, 15 May 1996 09:15:54 +0200 (METDST) From: Daniel Roth <[EMAIL PROTECTED]> To: Jordan Schwartz <[EMAIL PROTECTED]> Cc: Sundiallers List <[email protected]>, [EMAIL PROTECTED] Subject: re: sundials (fwd) In-Reply-To: <[EMAIL PROTECTED]> Message-Id: <[EMAIL PROTECTED]> Mime-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII
