Crown of Sancho IV

The two Roman cameos, dating back to the 1st century CE, depict portraits of Drusus the Younger and Queen Omphale, covered with the skin of the Lion of Nemea.

[1] The crown was mentioned for the first time in the will of Alfonso X the Wise on 21 January 1284:[1] [...] e las coronas con las piedras e los camafeos que lo haya todo aquel que con derecho por nos heredase nuestro señoría mayor de Castilla y León.

And when it might be God's will that we shall perish, we order that we be entombed in that place we arranged with archbishop don Gonçalvo and the dean Miguel Ximénez[...]On the death of King Sancho IV on 25 April 1295, he was buried in a chapel of the Cathedral which the king himself had ordered be built, and to which he had transferred the remains of all other monarchs buried in Toledo.

[2] The crown was found in 1948 during the search for the tomb of Sancho II of Portugal in the high altar area of Toledo Cathedral.

[2] The corpse of a man, of tall stature, appeared open, for in the process of sepulchral corruption the soles of his feet, which ordinarily form an angle with his legs, were shown to have fallen forward; he also wore a crown of eight links, supported by a hempen cord which, like a chinstrap, passed under his chin.
