_Haham_ Jacob Judah Aryeh _de_ Leon [Templo] of _marrano_ origin, was born in Hamburgh in 1603. Here for some years he was teacher in _Hebrew_ and _Rabbinics_ to the _Kahal Kadosh de Talmud Torah_. Subsequently he was appointed _Haham_ of Middelburgh in Holland, where in 1642 he published tracts in Spanish¹ and Dutch,² describing a model he had constructed of Solomon’s Temple. Shortly after he settled in Amsterdam and resumed his tutorial profession, and it was here that a French version³ of the tract was published, and seven years later a _Hebrew_ edition appeared,⁴ translated by the Author from his original Spanish. Versions in German,⁵ Latin,⁶ and _Ladino_⁷ have also been issued at various times. In anticipation of his visit to London to exhibit his model before Charles II. (1630‒1685) and his Court, he prepared an essay in English, which was printed and published in Amsterdam,⁸ describing the model of Solomon’s Temple, and also that of the Tabernacle of Moses, of which he had also constructed a model. It was again on view here in the years 1759 and 1760.⁹ In 1778 it was in the possession of a Mr. M. P. Decastro, who claimed to be a near relation of _Haham de_ Leon. He exhibited the model here, and translated and published the essay describing it,¹⁰ which he tells us was “First printed in _Hebrew_ and Spanish.”¹¹ ¹ Retrato Del Templo De Selomo.... _Compuesto, por_ Iaacob Ievda Leon Hebreo, _vezino de Middelburgo, en la Provincia de Zelanda_.
