Ardon Windows, Stained glass triptych at National Library of Israel, Jerusalem.

The Ardon Windows, also known as "Vision of Isaiah," are a stained glass triptych 17 meters wide and 6.5 meters high on the entrance wall of the National Library of Israel in Givat Ram, Jerusalem. Mordecai Ardon designed the work, which was executed by Charles Marq at Atelier Simon in Reims between 1982 and 1984. The three panels depict Isaiah's vision of universal peace: paths inscribed with the verse "Let us go up to the mountain of the Lord" in Latin, Greek, and Arabic; a red sky with the verse "Your hands are full of blood"; and white plowshares forged from swords above fragments of modern weapons.

Mordechai Ardon began preparing the work at the end of 1980, and the glass was made over four years, in 1982–84, under his supervision at Atelier Simon in Reims by Charles Marq. The project was made possible by the contributions of Ephraim and Tzipora Eilin. Ardon painted the cartoon after his wife Miriam died in 1981; a soul candle for her appears in the lower left corner.

Ardon took his subject from Isaiah 2:2–4, the vision of nations streaming to Jerusalem. In the left panel the verse "Let us go up to the mountain of the Lord" is written along paths in Latin, Greek and Arabic letters; the central panel sets a blood-red sky against a blue Kabbalistic tree of the sefirot, which Ardon first saw in 1949 in drawings in Yeshayahu Tishbi's translation of the Zohar. The wall of Jerusalem below is shaped from the Isaiah scroll found at Qumran.

You can view the windows during regular opening hours of the National Library in the Judaica reading room foyer. Natural daylight enhances the full color intensity of the glass panels for the best viewing experience.

In the lower-left corner of the left panel Ardon painted a ner tamid, the soul candle, in memory of his wife Miriam, who died in 1981; painting the window helped him recover from her loss. The work measures 17 by 6.5 metres and was made at Atelier Simon in Reims by Charles Marq between 1982 and 1984, funded by Ephraim and Tzipora Eilin. On 17 April 1990 the postal service issued two stamps and a commemorative sheet showing parts of the window.
