‘Medieval studies’ gives little away. ‘In honour of Peter Linehan’ offers a major clue. This splendid collection of essays is dedicated to a scholar who has profoundly influenced the study of the ecclesiastical history of the medieval Iberian Peninsula. Mindful of the themes of The Spanish Church and the papacy in the thirteenth century (Cambridge 1971), Ayala Martínez offers two unpublished crusading bulls of Honorius iii from the cathedral archive of Toledo, while Jerez publishes annals from the archive of Segovia which confirm just how few Franci were at Las Navas in 1212, as well as indicating the extent of the famine in Castile in the aftermath of victory. The brilliantly sophisticated if not downright foolhardy arguments presented by Archbishop Martinho Pires of Braga to Innocent iii in his battles with Compostela are carefully edited by Branco in an exquisite article which has broad implications for how papal power was viewed in the provinces. The failure of the post-Lateran IV papacy to part the Iberian clergy from their concubines, famously described by the honoree, is brought home by Paravicini's publication of the Dominican savant Guillaume de Moerbeke's authorisation of the absolution of one such culpable cleric. Many of the chapters here treat the concerns of History and the historians of medieval Spain (Oxford 1994). On the basis of palaeographical evidence, Henriet skilfully dates the Cluniac sections of the Liber canticorum et horarum to the time of Sancha, wife of Ferdinand i of Castile, and in doing so suggests that the Hispanic and Roman rites may have then lived happily together at court. Martin argues that the Carmen Campidoctoris was composed in the lifetime of the Cid, and not by a Catalan but rather by the celebrated Bishop Jerónimo himself. In similar fashion, Rodríguez Porto, using its illustrations, re-dates the Codex Calixtinus to the period of the Second Crusade and the growing Compostelan rivalry with Toledo. Alonso Álvarez explores how theological changes during the twelfth century concerning Christ's recovery, after the Resurrection, of his shed blood, may have transformed the relics of the holy blood in the cathedral of Oviedo into relics of the blood of the image of Christ Beirut. This article is complemented by García Avilés and Martínez Ruipérez's examination of the manner in which the Aristotelian philosophy of the schools altered the depiction of nature in art from the thirteenth century onwards. Happily, and necessarily, Don Lucas of Tuy makes an appearance through Falque's study of a manuscript of the Castilian version of the Chronicon mundi, used by Puyol in his edition. Hijano looks at the composition of the influential Crónica particular de San Fernando and its probable authorship at the court of Fernando iv, while Benítez Guerrero provides the first edition of the prologue of the Crónica de tres reyes, based on the twenty-seven manuscript copies. Other contributions, such as Conde's description of the dispute between the nuns of Las Huelgas and the Hospital de Rey call to mind the morally and politically fraught world of The ladies of Zamora (Manchester 1997). Dupont-Hamy edits a sermon of the late thirteenth-century Franciscan Juan Gil de Zamora which appeals to the powerful to love justice in times which, from his description, appear as iniquitous as our own, while Ladero guides us through medieval treatises on vice, culminating in Hernando de Talavera's La Breve forma de confesar, where sins are assiduously matched to the corresponding Commandments. Linehan's interest in the history of the Portuguese Church (Portugalia pontificia, Lisbon 2013) and his various forays into the later Middle Ages, most recently in At the edge of the Reformation: Iberia before the Black Death (Oxford 2019), are also treated. Vilar plots the path to power through family and court of Martinho de Oliveira, archbishop of Braga. Nickson and Cros Gutiérrez uncover the cuaderno in the Toledan archive which demonstrates Gil de Albornoz's efforts to set up a confraternity to raise funds after the collapse of the south tower in 1345. Hernández Farelo provides a detailed itinerary through Portugal of the papal collector Bertrand de Mazel from 1368 to 1371. Hernández describes the extraordinary intricacies of the propaganda war between Juan Manuel and Alfonso xi during the crisis of 1336 as they aimed to manipulate the historical record. Zutshi's masterly analysis of the international and local background to John i of Castile's decision at Medina del Campo to back the antipope Clement vii during the schism also provides much of value on the expansion and extent of the influence of Romano-canonical procedures in the Peninsula. Carmona Ruiz's study of the disputes, across centuries, between the concejo of Baeza and the bishops of Jaén over the village of Canalejas remind us that while people may come and go the rights of corporations are forever. Peter Linehan has not given so much of his time to the affairs of the Crown of Aragon but when he has done so, for instance in Spain 1157–1300: a partible inheritance (Oxford 2008), he has been content to use the sixteenth-century chronicler Jerónimo Zurita, whose remarkable work as historian and philologist is here scrutinised in the articles of Bautista and Torra. No less industrious than Zurita, although less well-organised, was the dedicated historian of the Bellpuig school, Jaume Caresmar, whose work, Freedman argues, was of significance for the development of Catalan historiography and provides us with much information on documents lost from the Napoleonic wars onwards. And while Caresmar conserved the history of the Premonstratensians and the Catalan Church, far away at Compostela, as Sánchez Ameijeiras reveals, the canons, worthy successors to Diego Gelmírez, were fighting new battles with old forgeries as Santiago and King Ramiro rode to the rescue against the duke of Arca, who had cast doubt on the validity of the ex-voto. This whole collection leaves one in no doubt that there remain riches galore in the Iberian archives which Linehan has so effectively mined for the reconstruction of the past, as well as historians with the ability to exploit them.
