Antonio de Alloytiz was the most outstanding architect of the altarpiece during the 17th century in Vizcaya, to which his knowledge of the sculptural style of Gregorio Fernández and his contacts with the altarpiece architect Pedro de la Torre contributed. We study his relationship with Torre and other court architects such as Bernabé Cordero and the Jesuit Francisco Bautista, his numerous trips to the court, where his business dealings led him to buy and sell a chapel in the convent of Santo Domingo el Real, acting as an intermediary in the context of a complex lawsuit. We also attribute to him two works conserved in museums and related to Madrid for different reasons, a monstrance from the Diocesan Museum of Sacred Art in Bilbao, which belonged to the disappeared main altarpiece of the parish church of Ochandiano, and an Immaculate Conception in the National Archaeological Museum, possibly from an altar in the church of Gordejuela.

The aim of this study is to research and analyse the 15th-century panel paintings in the National Archaeological Museum, whose artists’ names are well known. These works reveal the stylistic evolution of the Spanish schools, in which the Italo-Gothic, International and Flemish artistic currents are represented.

The aim of this research is to complete the work published in 1997 in the Boletín del M.A.N., thus fulfilling the aim of making known the complete collection of 15th-century panel paintings in the National Archaeological Museum. This article includes the anonymous 15th-century paintings and those attributed to the masters of Osma, Paredes de Nava and San Nicolás.

Poetry of an amorous nature, composed and performed by troubadours, played an important role in the courtly spheres of Europe from the 11th to the 14th centuries. This importance is reflected in various sumptuary objects whose function is closely related to their own iconography, with the gallant and playful themes typical of the troubadour universe taking precedence. The most outstanding known pieces are analysed, such as amatory boxes and chests, made of various materials such as polychrome wood or covered with embossed metal sheets, as well as the most sumptuous pieces made of ivory, among which we also find other important objects such as mirrors.

The movement of the sun in the sky, the succession of days and nights, the astonishing spectacle of millions of stars shining in the blackness of space, were questions that preoccupied man ever since the light of intelligence shone in his mind. This is a brief history of their astronomical discoveries up to the Middle Ages
