By way of Accion Liturgica, which in turn came from LexOrandi.es, comes word of the celebration of the Hispano-Mozarabic rite (since it is likely to be asked, I would presume this would be in accordance with the post-conciliar Missale Hispano-Mozarabicum) by the Archbishop of Toledo, D. Braulio Rodríguez Plaza, in the presence of Eastern Orthodox metropolitan Policarpo Stavrópoulos, celebrated on the feast of St. Ildefonso of Toledo and coinciding with the Week of Prayer for Christian Unity.
In his homily, the archbishop made reference to the Mozarabic liturgy, commenting that "the Hispano-Mozárabe liturgy is very expressive and moves us by its spirit and its deep spirituality."
Of historical interest, the chasuble and dalmatics worn (see below) are from a set which belonged to Cardinal Francisco Jiménez de Cisneros. (d. 1517)
Here are a few photographs from the Mass.
