Photos of the sundial:
Sundials are different according to where on the earth’s curved surface of their establishment.
The view itself in the sundial consists of different lines to indicate the time of year and time of day.
The time of year is shown by three main lines, which is the – summer solstice line – equinox line – and the – winter solstice line. Between summer and equinox are two intermediate lines with approximately 30 days apart and between equinox and winter in the same way between two lines. these lines follows the solar year, which is symmetrical about the solstice lines.
Calendar consisting of months, are not symmetrical about the solar year around – there is about 10 days on the winter solstice and New Year – therefore it is better to specify the lines whith the zodiac.
The time of day is shown by the loops – why is it loops and not lines? – it is because the sun moves in an ellipse, not a circle around the sun, the speed is higher near the sun and less distant from the sun, this means that when you measure the time with an accurate clock, what we do today, this timelab has a meaning – in the past, when watches were not common, it did not matter by 10 – 20 minutes.
If you look at the sun shadow a certain time every day of the year, it will follow this loop curve around, but which way round? – ! – If you stand in front of the sundial with the sun in the back, then the first three month is to the left curve, the second quarter will be the right curve etc.
I have made a machine that is set to draw the sundial with a lacer – the lacers beam hits the solar direction at different times of the day and the year.
Sundial manufacturing on a courtyard with ceramic indications – a table – on a wall – or in a garden.
You can also use the machine to predict at what times there will be sun in a particular location.
The sundial can be large or small depending on your preference.
The sundial could also be a bowl of a certain size.
Bowl sundials known from archaeological finds, thousands of years old.
