The Feathered Serpent is a British children's serial[2] costume drama[1] television series made for ITV by Thames Television, set in pre-Columbian Mexico and starring Patrick Troughton as the scheming High Priest Nasca.

Kukulkan is attempting to form an alliance with the Toltecs (who worship Quala and not Teshcata), through a dynastic marriage between Chimalma and Heumac, the object of which is to convert Kukulkan's people from the religion of Teshcata to that of Quala.

This struggle results in the abolition of the religion of Teshcata; the defeat of Nasca, who is walled up in his own secret passages inside the walls of the palace; the restoration of religion of Quala; the marriage of Chimalma and Heumac, and their coronation with the two crowns of Chichen Itza.

[7] The Feathered Serpent is related to Doctor Who serials including The Aztecs and Planet of the Spiders.

The wedding gown was a modified version of the winning entry submitted to a competition in Look-in, which was designed by Simon Theobald.

[5] The Feathered Serpent was first broadcast on ITV (including STV and Ulster) on Mondays from 21 June to 26 July 1976 and from 3 April to 8 May 1978.

[38] A 2 Disc set of Region 2 DVDs containing both series of The Feathered Serpent was released in the UK by Network Distributing in February 2009.
