Note 4 — EXPLANATORY LIST OF ILLUSTRATIONS TO VOLUME I. (continued 2)

See Fragm. Hist. Pisan. in Muratori, xxiv. 651, seqq.; and Caffaro, id. vi. 588, 594–595. The cut in the text represents a striking memorial of those Pisan Prisoners, which perhaps still survives, but which at any rate existed last century in a collection at Lucca. It is the seal of the prisoners as a body corporate: Sigillum Universitatis Carceratorum Pisanorum Janue Detentorum, and was doubtless used in their negotiations for peace with the Genoese Commissioners. It represents two of the prisoners imploring the Madonna, Patron of the Duomo at Pisa. It is from Manni, Osserv. Stor. sopra Sigilli Antichi, etc., Firenze, 1739, tom. xii. The seal is also engraved in Dal Borgo, op. cit. ii. 316.
