Yester-day was Friday and to-day, Saturday – according to my calendar from Santissima Trinità dei Pellegrini! Yes, it really did say the last five days of November ran Friday, Saturday, Sunday, Friday, Saturday. Oh well.
Similarly, yester-day Lauds had five psalms and two canticles – because I read the psalmody of Lauds I before realizing it should have been Lauds II (with five different antiphons, plus Ps 50 and Is. xii, 1-6 instead of Ps 46 and I Par. xxix, 10-13), so before the little chapter I read the psalm and canticle and antiphons I'd missed. Oh well.
Errare humanum est et confiteri errorem prudentis. (To err is human and to admit the error is wise.)
To-day is St Andrew's Day, isn't it? Third time lucky: I did remember to make a commemoration of Advent at Lauds.
