About this source
What it is
This is a large horizontal mural by John Henry Amshewitz, painted in 1936. It shows a crowned king on a red throne under a banner with a cross, with robed clergy, armoured men, sailors, a kneeling figure and a ship with sails in the background. According to the record, it shows Abraham ben Samuel Zacuto presenting his astronomical tables to da Gama before he left Lisbon in 1497. The mural is held in the William Cullen Library at the University of the Witwatersrand, Johannesburg.
Why it matters
The mural places Gama's departure in a crowded court scene. It shows the role of astronomy and of Jewish scholars like Zacuto in the preparation of long sea voyages. Painted in 1936, it also reflects how an artist of that period chose to present the Portuguese past.
