Fragment from the left side of Block XXIV that preserves parts of a horse’s and its rider’s legs. Another fragment (Ακρ. 1168) comes from the upper left corner of the same block. Block XXIV, the details of which are known to us thanks to a drawing attributed to Jacques Carrey, depicts two horsemen who are conversing as they move to the viewer’s right, as well as part of a third horse following them. Fragment Ακρ. 7417 belongs to this third horse and its rider that continued on the following Block XXIII kept today in the British Museum in London.

The frieze on the south side of the Parthenon depicts part of the procession formed by the people of Athens during the Panathenaic festival in honour of the protectress of the city, Athena. The procession's destination was the Temple of Athena Polias on the Acropolis. Its purpose was the transportation of the Panathenaic peplos destined to adorn the age-old xoanon of the goddess and the offer of a grand sacrifice of animals at the Great Altar outside of the temple.

On the south frieze the procession moves along the Panathenaic Way. Youths that lead sacrificial young cows precede. They are followed by more young men who carry offerings. Behind them come musicians with guitars, officials holding olive branches, eleven chariots that participate in an equestrian event, and finally sixty riders divided in ten groups.

The south frieze is fragmentarily preserved due to the bombardment of the Parthenon by the Venetians under the command of general Francesco Morosini in 1687 which caused extensive damages to the middle of the long sides of the temple. The drawings attributed to the painter Jacques Carrey, who visited the Acropolis in 1674, just thirteen years before its bombardment by Morosini, are an invaluable resource for our understanding of quite a few parts of this side of the frieze (Blocks XX - XXXVIII). Three blocks (XXII, XXX και XXXVIII) were already lost by then as they were removed during the conversion of the Parthenon into a Christian church so that windows would be opened in the blocks' positions.

The initial length of the south frieze was 58.70 m and consisted of 47 blocks. Today the blocks are divided between the Acropolis Museum and the British Museum in London, where they ended up after they were removed by Thomas Bruce, the lord of Elgin, in 1801-1804 when Greece was still under Ottoman occupation. In order to facilitate their transportation, Elgin's workmen, cut off with saws or crowbars only the faces of the blocks that bore the relief decoration. The Acropolis Museum exhibition includes the plaster casts of these blocks' faces on which some of the original fragments that fell off the monument, and thus escaped the looting, have been adjusted.
