||Snow 1977, no. 159 bis: "This article in five parts, despite the dates in its title, covers only the period of Alfonso's reign. The first part explicates CSM 328 as showing Alfonso's predilection for Puerto de Santa María, since documents show that this cantiga has much historical accuracy. The second part takes up the Military Order of Santa Maria de España which Alfonso founded and which had one of its four bases in Puerto de Santa María (see also Pérez Villamil , and Menéndez Pidal ). Alfonso's special patronage of the city is developed in part three, through the texts of CSM 358, 364, and 367. The latter poem is fully explicated in part four, which also implies that Alfonso was sole author of the CSM. The last part lists 22 CSM written by Alfonso as the 'juglar' of Puerto de Santa María: 328, 356-9, 364, 366-8, 371-2, 375-9, 381-2, 385, 391, 393, and 398 (he omits two others, 389 and 392).
