among the Antients. 163 



A horse, when trotting, lifts at ihe same time the right fore 

 foot and the left hin;i foot, which makes a double beating. 



We see these three kinds of movement? upon medals and 

 bas-reliefs; but statues whieh require a support of three feet 

 are susceptible only of the second. 



After the restoration of letters the art of founding re-ap- 

 peared in Italy in the time of the Medici. The painter An- 

 dre Verrochio was the first who inuigined that the antients 

 made ahollow mould upon a statue, or even upon a dead or 

 living subject, in order to form. an e.xaet resemblance. This 

 invention" naturally inspired him with the idea of using 

 a similar mould for melting a bronze st-tue : he suc- 

 ceeded, and exercised the art of founding in the manner of 

 the antients, i. e. by casting the parts separately and joining 

 them afterwards by'soldering. He undertook an equestrian 

 statue of a Venetian general to be executed in this way. But 

 he finished the horse only, having died of a malady con- 

 tracted from his zeal to execute the work with fidelity. Af- 

 ter this, John of Boulogne made use of the same method 

 for casting the equestrian statue of Cosmo de Pvledicis at 



Florence. 



About the year 1500, Pomponius Gauricus* printed at 

 Naples a treatise upon sculpture, in which he described the 

 ingenious method of proceeding nuule use of at present for 

 melting equestrian statues at a single cast. He adds m 

 the conclusion, that this science havm^ perished with those 

 who had formerly known and practised it, he thinks he is 

 enlilled to assume' to himself the n»erit ot the invention f.
