The Greek is to be pronounced as HÊ TO CHRONOO SKIA
This dial on a 220 cm x 65 cm slate is facing the North with an inclination equal to 15.6°. This is the angle of the Sun rays on Dec, 21th at noon. The sun is at the highest on that day, but the lowest relative to the rest of the year. The rays touch the surface of the dial only at that time, the rest of the day they stay below.
During Spring and Summer the sun reach the surface of the dial during the period between sunrise and sunset. The rest of the year it does this only during a part of this period. This part becomes shorter every day until Dec, 21th. On that day the contact only occurs at noon.
The house inhabitants see the sun on the dial the whole year, but barely on Dec, 21th.
The style that brings the shadow is pointing, as always with a polar style sundial in the Northern hemisphere, to the North. SO, it it has an angle with the dial table equal to 51 + 15.6 = 66.6°
The owner, Jos Venken, has also translated the motto inti Greeks and Latin to react against the abandon of these classical languages in the teaching.
