Origin of herpetological name of rattlesnake on the Gadsden flag.

Eastern Diamondback Rattlesnake

Crotalus adamanteus PALISOT DE BEAUVOIS, 1799

It is a venomous pit viper found in the southeastern United States. It is the heaviest venomous snake in America and the largest rattlesnake. It featured prominently in the American Revolution, specifically as the symbol of what many consider to be the first flag of the United States of America, the Gadsden flag which was designed by Christopher Gadsden (1724-1805) 1, the principal leader of the South Carolina Patriot movement during the American Revolution 2.

According to tradition, the Gadsden flag’s rattlesnake is Crotalus horridus Timber Rattlesnake 3. However, the dorsal coloration patterns of the vast majority of drawings made on this flag and geographical distribution of this viper species where this flag was designed around 1775, frankly are more consistent with Crotalus adamanteus Eastern Diamondback Rattlesnake (from Greek krotalon which means “rattle” and adámas “invincible” or from Latin adamanteus “diamond or lozenge-shaped”, referring to the shape of the dorsal body markings).

In fact, the two oldest banners from original Gadsden flag delivered in 1775 to Commodore Esek Hopkins by Christopher Gadsden in Pennsylvania and a replica of this flag in 1776 to South Carolina State Congress in Charleston, feature the Crotalus adamanteus rattlesnake. Likewise, the oldest banner of this flag that is in the Charleston Museum in South Carolina, presents this same species of rattlesnake.

Likewise, the type locality (site of the specimen (s) with which the species was originally described) of Crotalus adamanteus is restricted to Charleston, South Carolina 4,5. City where Christopher Gadsden lived. This further increases the likelihood that Gadsden was inspired by this local rattlesnake to design it.
